Boomsday Heal Zoolock

Use Void Ripper to get some last second burst. A keleseth buffed Doubling Imp hit with Soul infusion is a 3 mana 2 5/5's, and then if you put fungalmancer on that they are then an 8 mana for 32 stats which is valued at over 10 mana. Crystallizer lowers your health so your heal can work with your happy ghouls. If you play Librarian Librarian Crystallizer Crystallizer Nethersoul Buster Nethersoul Buster, it's a 10 mana 34 stats deal 4 damage to your hero draw 2 cards. The draw is worth 2.5, the damage is worth -.5, so really you're paying 8 for this much board presence. The deck should be fast enough to beat the combo decks.
