Insatiable Gorgers

The whole bargain is in the discard. Five power for four mana is a fair-enough rate; the same body for the cost of a card you were already pitching is a different proposition, and that is what madness buys. The madness cost carries the same total value as the printed , just shifted a pip cheaper on the colored requirement, so you are not paying a premium to cast it from exile: you are converting a dead card in hand into a five-power threat at instant speed off a discard trigger. That timing is the real prize. Any deck built to dump cards (a looter, a rummaging cost on something else, a payoff that wants the hand empty) gets to deploy this in response, ambushing an attack step or punishing a tapped-out turn. The 5/3 body is the tell on the other side of the ledger: three toughness trades down to almost anything in combat, and the must-attack clause strips away your control of when it goes in. It swings into whatever the opponent leaves back, every turn it can. That forced aggression is the price against the cheap, flexible front end. This is fuel for a board that wants bodies fast and does not mind losing them, where the discard outlet is the engine and this is the thing that happens to hit for five when it gets fed. Outside that shell, the toughness and the mandatory attacks make it a liability; inside it, madness rewards exactly the hand-churning those decks were doing anyway.
