Reckless Deathrattle Priest

Use reckless experimenter into your draw deathrattles to cycle for a ton of draws. Use 3 mana Coffin Crashers to bring out Obsidian Statues and 2 mana cube those to destroy enemy minions and bring out even more obsidian statues. Voodoo Doll is a 0 mana destroy an enemy minion at the end of your turn, which is absolutely insane, Devilsaur egg is a 0 mana 5/5 at the end of your turn. But the star aligner combo is also in here for the memes; turn 5 reckless experimenter, turn 6 mechanical whelp into cube, which summons you two mechanical whelps and a 7/7, Turn 7 trade one or two of the 2/2 mechanical whelps and play Star Aligner and now you've dealt 7 damage to all enemies so you're way ahead. This is also a dream scenario though. With a freshly summoned Obsidian Statue from the previous turn and reckless experimenter, you can play umbra into cube on the statue to flood your board with four Obsidian Statues and kill 5 enemy minions (1 from the cube battlecry, 2 from the first cube deathrattle's summoning, and 2 from the death of the cube). It's an insane deck if Reckless Experimenter can survive a turn or two.
