Dispeller's Capsule

In Commander, Dispeller's Capsule earns its slot in artifact-recursion shells — anywhere else it's a serviceable budget answer that competes with strictly faster options. Pauper is where it sees the most dedicated play outside Commander; the format's slower clock makes the two-mana activation cost acceptable, and the sacrifice clause matters less when you're not fighting through counterspell-heavy blue decks on turn two. In Legacy and Vintage the card is legal but irrelevant — Swords to Plowshares, Force of Will, and same-turn speed define those formats, and a tap-out removal piece with a delayed activation doesn't make the cut. Modern has Prismatic Ending, Leyline Binding, and a dozen other options that cost the same or less and resolve immediately, so Dispeller's Capsule doesn't show up there either.
