Quest: Kill 15 opponent's minions. Hmm, this might take me more than one game.
My opponent is playing Temur Elementals and they create a 16 stack of 2/2 zombies. I have Kaya's Wrath in hand. That felt good.
If I've got that quest, I always let an enemy Krenko buff up when I've got a Chainwhirler in hand. I don't even care if I lose because of it.
