Key Tactics

Dig hard for Kraken, he’s your only real win condition. All your other cards exist to delay until you draw him or protect him once he’s out.

Make sure you keep one source (or Elemental) ready when you play Kraken to protect him with a Submerge, Ice Sheath, or at worst a single point of water source power against a Blood Boil.

If you’re opening with elementals to ramp, Osvult’s free Ice Wall can buy you time until you’ve set up some defences. It also provides free source when you return the Ice Wall to hand with a source explosion; which also heals the wall.

Want to challenge yourself? Play this deck without source exploding. One Lesser Water Elemental provides just enough to protect Kraken for a turn if you devote all five sources to summon it.
