A five-mana 5/5 is slow, but a token-heavy Rakdos sacrifice shell can turn its ETB into removal plus an Army; likely a fringe payoff.

Could be wrong if Unrevealed sacrifice fodder and payoffs may be strong enough to create a dedicated shell.

Pioneer's efficient removal and faster engines make a five-mana board-dependent payoff hard to justify without unusually strong sacrifice fodder.

Could be wrong if A resilient sacrifice shell with plentiful expendable creatures could make the ETB worth testing.

Five mana, two colors, and another creature are steep asks in Modern; its ETB cannot hit players and compares poorly with cheaper interaction.

Could be wrong if A sacrifice or reanimation shell with large expendable bodies could exploit the damage and Army output.

Legacy's mana and interaction demands are prohibitive for this board-dependent five-drop, and its legend status adds Karakas exposure.

Could be wrong if Fast mana plus recurring sacrifice fodder could support a narrow experimental use.

Aristocrats and token decks can convert a disposable high-power creature into removal and sometimes a large Army, but this is a one-shot five-mana payoff.

Could be wrong if Better repeatable sacrifice outlets or removal creatures may leave it too replaceable.

A 5/5 plus conditional creature kill is a strong swing with fodder; without it, a five-mana 5/5 remains playable. Revealed token density improves it.

Could be wrong if Its performance falls substantially if fodder, opposing creatures, or reliable BR fixing are scarce.
