General[edit source]

  • Zephrys' Battlecry allows the player to choose a card from the Legacy set to add to their hand from a selection of three cards, from any class. The three cards offered are based on what is best for the current gameplay situation, as calculated by an internal algorithm.[1][2]
  • The cards Zephrys can generate from the Legacy set are based on cards that were in the Basic and Classic sets before Patch 20.0.0.77662 and the introduction of the Legacy set.
    • Essentially, the following cards are not in Zephrys' pool, even though they are in the Legacy set:
  • Zephrys' algorithm will consider both players' board state, your available mana after playing Zephrys, your available mana for the next turn, both players' health totals (health and armor), both players' classes, both players' deck sizes, and how many cards are in your hand and in your opponent's hand.[3][4][5] Zephrys also considers the number of Secrets the opponent has, and the opponent's weapon if they have one equipped.[4] Zephrys also considers both players' Basic and Upgraded Hero Powers, but not most other hero powers.[5][6]
    • Zephrys will only use "public" information in selecting his card offerings, as detailed above; thus, he will not see or use "private" information, such as what cards are in your hand.[3][7]
  • In addition to looking at the board state, Zephrys also breaks down cards from the Legacy set into categories. Zephrys uses these categories to offer the player the best cards from the three best categories.[2][4][8] For example, Zephrys can offer one area of effect card, one single-target removal card, and one proactive card, such as a reasonable minion, in many situations.[2] Sometimes Zephrys will offer more cards of one category than the others if they are significantly better for the current board state.[9]
    • For example, if the opponent has enough minions on the board, Zephrys might offer three board clear cards.[2] Generally though, there is a threshold at which Zephrys keeps offering cards from the same category.[4]
    • For example, if the opponent has a Murloc, Zephrys is able to offer  Hungry Crab to destroy it, but only if it is better than other single-target removal options considered by Zephrys.
  • Zephrys will only offer cards that the player can play on the same or following turn. He tries to prioritize the former but can also offer choices for the latter if he detects that he can give an especially useful option for the following turn.[1]
    • For example, if Zephrys is offering a board clear card, he may give  Twisting Nether if there is 8 mana left, or  Flamestrike if there is 7 mana remaining (and if enemy minions are mostly at 4 or less health).[1]
    • For example, if Zephrys is played on turn 7 and there are no other minions on the board, he is able to offer  Tirion Fordring to play on turn 8.
  • Zephrys will always offer cards to grant the player lethal if possible in the current turn.
    • However, because Zephrys doesn't know what cards are in your hand, Zephrys will only spot lethal if the player has already taken the necessary actions to set up lethal.
    • Lethal will also only be granted if it is within the limitations of Zephrys' coding (please also see the "Lethal" section below).
  • Zephrys only looks at "interesting" Legacy cards and will never offer "uninteresting" cards which players would rarely want, such as  Bloodfen Raptor.[1] There are a total of roughly 130+ cards that Zephrys looks at when considering what to offer for the player.[4] For gameplay reasons (i.e. wishing for more wishes[4]), he will also never offer cards with return to hand effects (namely  Shadowstep,  Youthful Brewmaster, and  Ancient Brewmaster).[10][11][12]
  • Zephrys understands normal game mechanics and basic keywords[13] (e.g. Taunt,[14] Windfury,[15] Divine Shield,[16] Poisonous,[16] Lifesteal,[17] Spell Damage[18][19][20]) but not special card text and effects (e.g.  Electra Stormsurge,[21] Deathrattles,[22]  Supercollider,[23]  Bomb Wrangler,[24] Kayn Sunfury[25]). He does, however, understand conditional effects (e.g.  Kill Command,[26]  Houndmaster[27]) and healing-into-damage effects (e.g. Auchenai Soulpriest[28]). Zephrys also understands offering a few Choose One cards for their Choose Both effects (e.g. with  Ossirian Tear).[29]
  • Zephrys is able to simulate what the game state looks like after some of Zephrys' offered cards are played on all possible targets. Zephrys then evaluates and compares the resulting game states after these targets have been "tested". Sometimes there might be simulations of waiting a turn to see what happens there. Holistically, Zephrys goes through a list of functions, one for each card that he offers, to obtain and compare resulting game states.[4]
  • Zephrys' Battlecry is similar to but not equal to a Discover effect, so it does not work with Discover-related effects such as  Dwarven Archaeologist.[30][31]

Offers[edit source]

  • Zephrys is able to offer area of effect and single-target removal cards based on the attack and health of enemy minions, whether or not enemy minions will significantly reduce in stats if silenced, and whether enemy minions have Reborn[32] or Deathrattle[32] effects. When offering removal options, Zephrys understands core gameplay mechanics and common keyword states, but does not read or understand unusual minion card text and effects.[13][33]
    • For example, if there are multiple minions on the opponent's board and they have 4 or less health, Zephrys is able to offer  Flamestrike.[34]
    • For example, when offering a board clear card, Zephrys may offer  Brawl if there is 5 mana remaining,  Twisting Nether to avoid the risk of any minions surviving, or  Blizzard if Zephrys wants to lock up the board.[2]
    • For example, if the opponent has a  Twilight Drake, Zephrys is able to offer  Earth Shock.[35]
    • For example, if the opponent has a  Lightspawn, Zephrys is able to offer  Ironbeak Owl.[36]
  • Zephrys recognizes enemy Deathrattles but does not understand the effects of Deathrattles.[37][38] Thus, when Zephrys evaluates whether to remove a Deathrattle minion, he first judges the minion's threat level by looking at its base mana cost, attack, and health, and then he compares these stats to the stats of a vanilla minion at the same mana cost. Zephrys then adds this difference in stats as a value to the opponent's board.[22] Chadd Nervig, one of the main designers of Zephrys, additionally stated on Twitter that, "it's a bit higher than just subtracting the stats."[39] For the cases when Zephrys decides to offer removal for an enemy Deathrattle minion, he will try to prioritize removal that won't activate the Deathrattle, such as with transform or silence effects, or  Sap.
    • For example, if the opponent has a 6/6 Pyros, Zephrys is able to offer  Hex to safely remove it without triggering its Deathrattle effect.[40]
    • For example, if the opponent has a  Khartut Defender, Zephrys is able to offer Hex to safely remove it.[41]
    • For example, if the opponent has a  Tortollan Shellraiser, Zephrys is able to offer  Sap to safely remove it.[42]
    • For example, if the opponent has a 5/7  Augmented Porcupine and Zephrys is played with 1 mana remaining,  Earth Shock is able to be offered.[43]
    • For example, if the opponent has a 4/5  Zixor, Apex Predator and Zephrys is played with 1 mana remaining, Earth Shock is able to be offered.[44]
    • For example, if the opponent has a 1/1  Boom Bot and Zephrys is played with 1 mana remaining, Earth Shock is able to be offered.
    • In general, Zephrys is able to offer Earth Shock to remove a Deathrattle minion that will have 1 health remaining after silencing, even if with enchantments it currently has more health. To absolutely guarantee Earth Shock, Zephrys should be played with 1 mana remaining, the player has 5 or more cards in hand after playing Zephrys (to compete with the single-target removal spell  Mortal Coil), the enemy Deathrattle minion is relatively high-cost with low base stats, and the minion is the only enemy minion on the board. Earth Shock is also able to be offered for 1-health Reborn minions.[45]
    • Also, Zephrys does not offer  Mass Dispel for a bunch of non-threatening enemy Deathrattle minions, such as a field of Leper Gnomes,[46][47] because Zephrys does not read card text and does not consider them worthy of being silenced. Zephrys also does not offer Mass Dispel for a bunch of health-buffed enemy minions that are low in attack and thus considered non-threatening to Zephrys.[48][49]
  • Zephrys is able to offer a myriad of specific counter cards such as  Acidic Swamp Ooze if the opponent has a weapon,  Flare if they have an active Secret,  Crazed Alchemist if they have a  Doomsayer, and  Hungry Crab if they have a Murloc.[50]
    • Zephrys, however, sometimes doesn't offer  Flare if the opponent has an active Secret,[51][52] and if there is 2 mana remaining to spend.[53][54] Zephrys is able to offer Flare if the opponent has five (a Christmas tree!) of Secrets,[55] but sometimes not when he thinks you have lethal through other means (but the Secrets actually make it impossible).[56][57]
      • Zephrys knows the number of Secrets the opponent has, but not what they are since it is not public information.[58] This means that Zephrys does not recognize the existence of specific Secrets such as  Counterspell and  Ice Block. Additionally, Zephrys does not prioritize Secret removal for Mage Secrets.[51][52][53][54]
    • Zephrys is able to offer  Harrison Jones against the Rogue class with the Rogue hero power even if they don't have a weapon equipped.[59]
    • Zephrys is able to offer  Bloodsail Corsair against Immune weapons such as  Stormhammer (which doesn't work).[60]
    • Zephrys knows how an enemy  Doomsayer works and the importance of killing it, so Zephrys will offer options accordingly upon seeing an enemy Doomsayer.[16][61] The developers don't plan to teach Zephrys about individual card mechanics and interactions, but this case was a one-time exception.[16]
  • Zephrys is able to offer burst damage that's not lethal in the form of  Bloodlust,  Savage Roar, Windfury, and  Windspeaker if the opponent's board is not very threatening; however, if the player has a lot of minions on board and lethal is not close in reach, Zephrys will prefer to offer  Soul of the Forest instead.[62]
    • Example: The opponent has a 3/3 minion. Bloodlust is offered with 5 mana remaining for +15 attack to reduce the opponent to 1 health.[63]
    • Example: The opponent has no minions. Savage Roar is offered with 3 mana remaining for +14 damage to reduce the opponent to 3 health.
    • Example: The opponent has no minions. Savage Roar is offered with 4 mana remaining for +8 damage to reduce the opponent to 2 health.[64]
    • Example: The opponent has no minions. Savage Roar is not offered for +12 damage to reduce the opponent to 8 health, but Soul of the Forest is offered.[65]
    • Example: The opponent has a 6/6  Kronx Dragonhoof. Bloodlust is not offered to reduce the opponent to 1 health after Zephrys is played with 5 mana remaining.[66]
    • Example: The player has a 6/6  Edwin VanCleef and the opponent has 28 health and no minions. Windfury is offered after Zephrys is played with 2 mana remaining.[67]
    • Example: The player has 3 minions and the opponent has a 2/1  Guardian Augmerchant. Windspeaker is offered for the player's 6/3  Rotnest Drake to reduce the opponent to 3 health, but Savage Roar was not offered to reduce the opponent to 1 health.[68]
  • If the player is very low on Health, Zephrys will commonly offer several healing or survival options, such as  Healing Touch.[69] However, Zephrys will not always offer the most optimal option for healing or survival when the player is low on Health and in danger of dying.
    • Example: The player is at 10 health. Zephrys is able to offer Healing Touch for +8 health with 6 mana remaining.[70]
    • Example: The player is at 10 health. Zephrys is not able to offer Healing Touch with 5 mana remaining, but offers  Acidic Swamp Ooze to destroy the opponent's 5-Attack weapon. On a minor note, if Zephrys had offered Healing Touch, the opponent would not go on to gain lethal in the next turn.[71]
    • Example: A Priest player is at 1 or 2 health with a  Lesser Heal hero power. Zephrys is not able to offer any healing or survival options such as  Holy Light for the current turn after Zephrys is played with 2 mana remaining, but offers Healing Touch for next turn.[72][73]
    • Example: A Priest player is at 8 health with a Lesser Heal hero power. Zephrys is not able to offer  Holy Light with 2 mana remaining, but offers  Lay on Hands for next turn.[74]
    • Example: The player is at 11 health and the opponent has 12 attack on board with 3 out of 5 minions having greater than 2 health. Zephrys offered  Soul Cleave but not  Frost Nova as his area of effect choice.[75]
    • Example: The player is at 1 health. Zephrys is not able to offer  Lightning Storm with 3 mana remaining, which has a 50% chance of clearing the opponent's board and prevent 10 damage from minion attacks, but may offer Frost Nova.
  • Zephrys is able to understand offering Combo cards for their Combo effects.
  • Zephrys is able to offer minions based on their reduced costs, such as  Dread Corsair and  Sea Giant.
  • Zephrys is able to offer  High Inquisitor Whitemane to summon minions that died in the current turn if Zephrys is played with 7 or more mana remaining.[78]
  • Zephrys is able to offer  Twilight Drake if there are at least 5 cards in hand after playing Zephrys.
  • Zephrys is able to offer  King Mukla to mill the opponent,[79][80] or if the opponent's hand is full.[81]
  • Zephrys is able to offer  Sap to destroy an enemy minion when the opponent's hand is full.[82]
  • Zephrys is able to offer  Shadowflame to play on himself to deal his attack damage to all enemy minions,[83][84] or to play on another minion to deal that minion's attack damage to all enemy minions.
  • Zephrys is pessimistic about random-targeting cards that he offers in order to be safe.[85]
    • For example, when Zephrys offers  Brawl, he assumes the median enemy wins.[85]
  • Zephrys frequently offers  Tirion Fordring as a proactive lategame card.
  • Zephrys is able to offer  Alexstrasza if the player is ahead on board with roughly at least 10 attack,[86] the opponent's hero has more than 15 health, and there is at least 9 mana remaining after playing Zephrys. However, Alexstrasza cannot be offered in some Solo Adventures such as Tombs of Terror.[87][88]
  • Zephrys is able to offer  Lord Jaraxxus if the player's hero is below 15 health and the opponent's board state is not too threatening.[89]
  • Zephrys is able to offer  Faceless Manipulator if there is at least one big-statted minion on the board controlled by the player or by the opponent.[71][90] Faceless Manipulator is more likely to be offered if the minion has Taunt,[70][91][92][93] Deathrattle,[41][94][95] Charge,[96] or any other valuable common keyword state.
  • Zephrys is likely to offer cards for card generation or card draw if the player has 4 or less cards in hand and the opponent's board is not very threatening.
  • Zephrys does not offer cards for card draw if the player's deck is empty or near empty, but is able to offer cards for card generation instead, such as  Ysera,  Brightwing, and  Thoughtsteal. Zephrys considers offering Thoughtsteal only if the opponent's deck has two or more cards.
  • Zephrys offers cards only on their base cost, so cost-modifying effects such as  Loatheb,  Sorcerer's Apprentice, and  Summoning Portal do not affect his offerings.[97][98]
    • For example, Zephrys may still offer  Twisting Nether if the opponent has played Loatheb.
  • Zephrys sometimes does not offer the same cards when a double-Battlecry effect is in play, such as with  Brann Bronzebeard or  Spirit of the Shark, simply because hand size is changing in between wishes.[27][77][99][100] Additionally, if a double-Battlecry effect is active, Zephrys does not know how to chain his Battlecries.[101]
  • Zephrys never offers cards for "unforced trading",[102][103] unless Zephrys is calculating lethal through enemy Taunt minions with cards like  Savage Roar or  Bloodlust, or if  Crazed Alchemist is involved as a single-target option.
  • Zephrys is able to offer silence cards in certain strange situations, which seems to be a bug.
    • Example: Zephrys is able to offer  Earth Shock for a lone  EVIL Totem when Zephrys is played with 1 mana remaining, but strangely not any removal card such as  Backstab or  Arcane Shot.[104]
    • Example: Zephrys is able to offer Silence when a Paladin opponent has no minions, and none of the player's own minions need silencing.[105]
    • Example: Zephrys is able to offer Silence when a Mage opponent has no minions, and none of the player's own minions need silencing.
  • Zephrys sees Titan minions as regular minions with stats. Zephrys would think that the Titans could attack, would not see the titan abilities, or their exhausted state, and would offer options accordingly.[106]

Lethal[edit source]

  • Zephrys will always offer cards to allow the player to gain lethal, even options that are unintuitive at first glance.
    • However, since he cannot see what cards are in the player's hand, he can miss lethal chances if the player does not play out their cards first.[107][108]
    • He will not offer lethal solutions that rely on RNG.[26][109]
    • He will only offer lethal within the limitations of Zephrys' coding. This page attempts to address all of his algorithm limitations.
  • Zephrys is able to find lethal with a Basic or Upgraded Hero Power.[5][110] Additionally, the modified cost and modified damage/healing of the hero power is also taken into account.[5]
    • Example: The opponent has 9 health. With 8 mana remaining, Zephrys is able to offer  Avenging Wrath in combination with the Mage hero power  Fireblast for lethal.[111]
    • Example: The opponent has 8 health. With 7 mana remaining, Zephrys is able to offer  Fireball in combination with the Hunter hero power  Steady Shot for lethal.[112]
  • Zephrys understands finding lethal with a healing spell such as  Healing Touch with  Auchenai Soulpriest on the board.[28] This also works with other healing-into-damage effects, such as with  Auchenai Phantasm or  Embrace the Shadow.
  • Zephrys is able to offer silence when he spots a lethal blocked by Taunt minions.[14][113]
  • Zephrys is able to offer silence if the player has a frozen minion on board capable of giving lethal if it was unfrozen.[5]
  • Zephrys is able to offer silence to reset a friendly minion's stats to gain lethal, getting rid of a set attribute effect.[114]
  • Zephrys is able to offer silence to silence a "Can't attack" minion if it would be lethal if the silenced minion attacks.[115]
  • Zephrys will favor silence cards among potential lethal options to help minimize unwanted interference caused by Deathrattles or other card effects.[5]
  • Zephrys is able to find lethal through fatigue damage.[116][117] However, before Patch 15.0.4, it was seen that Zephrys could miss finding lethal through fatigue if the opponent had the Warrior hero power. This bug might still exist in certain rare situations.
    • Example: Opponent Warrior hero is at 17 health, taking 10 fatigue damage next turn. Zephrys was not able to offer  Gorehowl for lethal.[27]
  • Zephrys is able to find lethal using  Prophet Velen's damage modifier effect.[118]
  • Zephrys is able to offer  Shadow Madness to be played on an enemy minion for lethal.
  • Zephrys is able to offer  Crazed Alchemist to be played on a friendly Elusive minion for lethal.[119]
  • Zephrys is able to offer  Alexstrasza for lethal if there is 9 mana remaining after playing Zephrys and lethal damage is presented on board after Alexstrasza's effect.
  • Zephrys is able to offer  Heroic Strike or  Inner Demon for a hero with Windfury to find lethal, such as if the hero is equipped with  Doomhammer.
  • Zephrys is able to offer  Pyroblast for lethal next turn if the opponent is at 10 health or below, or can be reduced to 10 health or below in the current turn with the player's current board state, and the opponent's Lifesteal minions, if any, are not able to heal the opponent out of range of a Pyroblast lethal next turn.[17][90]
  • Zephrys does not use active cost-reduction effects to find lethal.
  • Zephrys does not offer  Tundra Rhino for lethal.[122][123][124]
  • Zephrys does not offer  Timber Wolf for lethal.[123][125]
  • Zephrys does not offer  Blessing of Might for lethal.
  • Zephrys does not offer  Sinister Strike for lethal.[126]
  • Zephrys does not actively seek out lethal in the current turn if the opponent's hero is immune, such as from the effect of  Mal'Ganis,[127][128] but is able to offer Pyroblast if the opponent is at or below 10 health and they have no Lifesteal minions.[90]
  • Zephrys is able to offer  Baron Geddon for its end-of-turn effect that deals 2 damage to all other characters, but will not recognize using a Baron Geddon already on board to deal 2 damage to the enemy hero for achieving lethal.
    • Example: Baron Geddon is on the player's board and the opponent hero is at 8 Health. Zephrys is played with 4 mana remaining.  Fireball is not offered for lethal.[129]

Fixed bugs[edit source]

The following is a very brief list of some documented interactions that have been fixed. For the official patch changes, see #Patch changes.

  • With the live release of Saviors of Uldum, Zephrys now more correctly values Reborn effects and "egg" Deathrattles.[32] Previously in pre-release, Zephrys did not value these two card effects when offering board clear cards.
  • Before Patch 15.0.4.33402, Zephrys was able to find lethal with an unused Basic Hero Power, but sometimes not with a used Basic Hero Power.[131] After the patch, this bug was fixed.
    • Example:  Steady Shot is used, bringing the opponent down to 7 health with no minions on their board. Zephrys is played, leaving 6 mana available. Zephrys offered  Fireball, but Steady Shot was already used so it was not lethal. As a separate and overlapping bug, Zephrys was not able to offer  Avenging Wrath for lethal.[132]
    • Example:  Shapeshift is used, killing off a 1/1 Taunt. Zephrys is played, leaving 6 mana remaining. He does not offer any lethal options, such as  Bloodlust, which would give lethal with the minions on board. He does offer a  Savage Roar, which would give lethal if both the 1/1 Taunt was off the board and the player had not attacked with Shapeshift yet.[133]
  • Before Patch 15.0.4.33402, Zephrys was able to offer  Coldlight Seer with no friendly Murlocs on the field.[134]
  • Before Patch 16.0.0.37060, Zephrys overvalued the effect of Deathrattles by a lot, causing him to avoid destroying enemy minions with Deathrattles a little too much, instead preferring to offer freeze effects such as  Frost Nova and  Blizzard.[135][136][137] This was a large issue but was fixed after the patch. The change in Deathrattle evaluation was explained by Chadd Nervig on Reddit:[22]
"Previously, Zephrys valued Deathrattles as summoning a minion with stats equal to the difference in stats between the minion's base stats and the expected stats of a vanilla minion at that mana cost.
Now, instead of evaluating it as summoning a minion, it does something more generic, of adding 'that much value' to the opponent's board. In practice, this produces about the same results, except without the occasional card offered to deal with that extra summoned minion (which doesn't exist)."
