Meh. I doubt this will see any play. Maybe if it had taunt, those stats could be worth it. I like the flavor of the card. Reminds me of the abomination from darkest dungeon. Could see play in aggro maybe.
Very well statted for it's cost with an obvious large drawback. I can still see this card getting play (or at least be experimented with) in aggressive decks that don't care much about board control, or in spell heavy control decks since it can two for one on the board most of the time
Start of Year: Provoke the failure of 3 expansions, force nerfs on otherwise balanced cards, bring deckbuilding to an all-time low and get rotated one year earlier for being such a threat to the game's health. - Genn and Baku's historical entry on the White Book of Shit Design, shortly before retiring unpunished
I think it might have some really niche uses. For instance, if you're playing a spell heavy deck then you might not mind losing the board that doesn't exist (something like freeze mage or a combo priest). Also if you actually want your own minions to die then it might be a cute trick.
For instance, you steal a minion with Shadow Madness but can't make a perfect trade killing both minions off. This minion dies to another enemy minion killing off that extra minion which could be something like a deathrattle card draw. Then you get the card draw, minion dies, and you got a good stated minion with this. And yeah that's a dream scenario and not reality in 95% of cases but it's something to think about.
