At {1}{R} it only deals 2, far behind Lightning Bolt and Unholy Heat; larger instant-speed exile kills are possible but inefficient.

Could be wrong if A metagame centered on creatures needing damage-based exile, or a mana-rich red shell, could create a sideboard role.

Legacy's cheap removal outclasses a two-mana 2-damage spell; scaling does not offset the format's severe mana-efficiency demands.

Could be wrong if A red Ancient Tomb-style shell or unusually relevant death-exile target could support narrow adoption.

Flexible instant removal can efficiently kill medium creatures and exile them, but it remains damage-limited and weak against Commander-sized threats.

Could be wrong if Higher-than-expected recursion or death-trigger density could make the exile clause materially more valuable.

An instant that kills a 2-toughness creature for two mana or a 4-toughness creature for three, with exile upside, is premium flexible removal.

Could be wrong if Unknown creature toughnesses, speed, and removal quality could make its damage thresholds less reliable than expected.
