Mulligans
Aggro Mulligans
This deck performs incredibly well against aggro decks, as it runs tons and tons of AoE removals. You can easily play early Wild Pyro + 2 spells as a 2 dmg AoE (coin counts a spell), then Spirit Lash can clean the board again and gain you some life (works great with bloodmage thalnos). Also, Auchenai Soulpriest + Circle of Healing is a 4 dmg AoE. Of course after those, there's always Excavated Evil (3 dmg AoE), a Dragonfire Potion (5 dmg AoE) and Lightbomb. And in case there's a minion survived these, you play Shadowereaper Anduin and you win the game.
