Heal Zoo [THEORYCRAFT]

I'm not sure if nethersoul buster is worth having 2 copies. I cut one life drinker for a second copy of crystalizer. I considered soul infusion but I think that a 2/2 handbuff is too slow for this deck, but it's worth testing. If warlock can get another minion that summons a copy of its self like chain gang and doubling imp then I think soul infusion will be worth adding.
