Here's my entry for this week:
Pretty strong minion if you have a few small minions lying on the board. Perhaps a bit overcosted, but I believe it's okay. Could be used if you think your opponent has an AOE in hand, but is weaker to direct removals.
Warlock-only because the 'gain their attack and health' mechanism is one that only warlocks have. Also warlocks could use a dragon.
"People often say something that destroys your board can't be trusted, but that's 'nether' here nor there."
