Your goal is to get Humongous Owl onto the board, die, and then clone its Deathrattle onto a full board thanks to Tamsin's Phylactery. We get to cheat out cards through Runed Mithril Rod and Wicked Shipment is an excellent source of board fill.

Afterward, just kill off all your minions and win the game.

Variants of this deck:

Weapon Destruction

• Remove 1x School Spirits or 1x Full-Blown Evil
• Add 1x Rustrot Viper

If you need the removal consistency, you can get rid of both copies of Full-Blown Evil in exchange for two Rustrot Vipers.

Stay Healthy

• Remove 1x Mo'arg Artificer
• Add 1x Spice Bread Baker

I've seen this list a couple of times and HSReplay actually has data on it which shows it has success at Diamond->Legend. It can provide more healing potential than Mo'arg + Drain Soul combo but you lose the removal potential of Drain Soul. Still, only needing one card instead of two to heal on up is kinda neat.
