Pretty bad. Only way I could see this being played is a combo deck with deathrattle activators, that could help go through your deck pretty fast. Thinking of Malygos OTK Deathrattle Rogue with Necrium Vial and the weapon.
Reckless Experimenter is probably the only good synergy with this card. Outside of that, it is just too hard to get the effect of the card (especially since agro cards will run you down while you figure out how to activate it).
