Since I lack Pirate cards, I had to Mrglglgl three times.
The rest of the deck is filled with random spells just to be destroyed so we can draw better cards instead.
Mulligan: Go for the Murloc Tidecaller which is your MVP. If you draw any spells for your first turn, it would be wise to restart.
Turn 1-6: Clear his board, in order to keep the Tidecallers safe, and go face. Trade wisely.
Fingers crossed he doesn't cast Blizzard on his turn 6. If he does, then try again.
