Mulligans
General Mulligans
I put in low cost minions with high health as they usually help with trades early-on.Shieldbearer is the best bang-for-your-mana taunt I could find for the early game
Dirty Rat is a risk, but having 2/6 stats on board by turn 2 is great, it even has taunt, which is better
Shadow Word: Pain is there to answer your opponents' early board
Mana Geode is iffy, but in theory is should support the strategy
Fel Orc Soulfiend is a 3 cost 3/5
Museum Curator is just thrown in as draw, it might be cut later
Initial build
Exhaust your opponent with spells and bulky minions, heal any damage received, win.
