Mulligans
your opponent thinks you are a normal aggro murloc paladin who has gotten unlucky with his call to arms until turn 6 and wastes all his resources on clearing your small taunts and murlocs then gets wrecked when you start dropping spitefuls with 8 drops, tirion and lich king plus any other tirions you got off of stonehills then you finish him dropping one of your dinosize on a murloc or righteous protector.
edit: added stonehills for more taunts and the lich king for a big taunt that gives you spells for all these counterspell mages and possible weapons, board clears, health buffs and minion draw.
