Panic Attack

In Commander, Panic Attack is too narrow: it hits at most four creatures, does nothing at instant speed, and evaporates at end of turn, so it rarely generates the damage needed to matter at a four-player table. Pauper is its most viable home, where aggressive red decks can aim it at a single blocker to close a game on turns three or four — though even there it competes with strictly better options. Across Legacy, Vintage, and Modern it's unplayed, outclassed by effects that either affect the whole board or cost less mana. Panic Attack is a limited card that never made the jump to constructed relevance.
