To edit these notes, go to Template:Unstable Evolution notes.
- The new evolved minion will be exhausted by summoning sickness and unable to attack this turn, unless it transforms into a minion with Rush or Charge.
- For general notes on the mechanic, see
Evolve.
Trivia[edit | edit source]
- Unstable Evolution used to be "Repeatable this turn" instead of "Echo". This was changed because of
Radiance of Azshara which causes Unstable Evolution to discount its cost to 0 mana allowing the player to play infinite amounts of Unstable Evolutions in one turn. Unlike 
Radiant Elemental or 
Sorcerer's Apprentice, Radiance of Azshara is a Shaman card which can be included alongside Unstable Evolution which always reliability achieve this interaction. This change was made to pre-emptively prevent the interaction.
