Template:Swampqueen Hagatha strategy
Swampqueen Hagatha trades a low-tempo minion for a very value-efficient minion to use later. The Drustvar Horror can find spells way above its cost like 
Bloodlust, 
Rain of Toads, or 
The Storm Bringer or help fish for spells like Lava Burst or Hex to gain lethal or save yourself. It is generally well worth the cost and can find its place in control decks or midrange decks as a potential finisher.
The Drustvar Horror's Battlecry also works with 
Shudderwock, further empowering its Battlecry. Selecting non-targeting spells is advisable and avoid transformation or ally-damaging cards if you plan on using both.
Swampqueen Hagatha is extremely powerful when combined with 
Heart of Vir'naal or 
Brann Bronzebeard, allowing for creating two Drustvar Horrors and allowing them to cast twice as many spells. Note that picking a spell with Overload will cause it to be applied twice.
