Mulligans
N'Zoth, God of the Deep good enough with 3 minions, heal clear Walking Fountain, clear Fleethoof Pearltusk and double taunt Safeguard.
Y'Shaarj, The Defiler is ok for developing more board with rush and taunts.
Dunk Tank bullshit slow af card and blizzard should be ashamed for printing it. Not worth including even for Y’shaarj. Aggro will eat you alive for 4 mana deal 4 damage. Run Torrent instead.
Yogg cut (only 15 spells), Phaoris cut (N’zoth simply better).
