Narset's Rebuke

In Commander, Narset's Rebuke occupies a useful niche: it answers a problematic enchantment or artifact at instant speed while drawing a card, which keeps you from falling behind on cards when you tap out to interact. It won't stop a spell permanently, but in a format where games go long and card advantage compounds, cantripping removal is structurally better than a dead card in hand. In competitive 1v1 formats like Modern or Pioneer, the bounce effect is too slow — opponents simply replay the spell — and blue has access to hard counters that close games, so Narset's Rebuke rarely makes those lists. Legacy and Vintage have the same problem at a higher power level. Pauper is its most interesting competitive home, where card parity matters enormously and instant-speed bounce with a free draw can swing tempo decisively.
