Magmatic Sinkhole deals 6 damage for two mana — as long as you've cast or copied at least one instant or sorcery this turn, which in any spell-heavy deck is a trivially met condition. It's a premier removal spell in blue-red spellslinger builds, and the efficiency gap between it and generic six-damage alternatives is wide enough to make the delve cost almost irrelevant.

In Commander, Magmatic Sinkhole earns a slot in any deck that regularly chains spells in a single turn — Izzet spellslinger, storm, and cascade lists all activate it with zero setup. Pauper is where it's genuinely format-defining: 6 damage at common rarity clears almost every creature in the format, and blue-red spells decks there treat it as a staple. In Legacy and Vintage, the competition from Swords to Plowshares, Fatal Push, and Force of Will is stiff enough that Magmatic Sinkhole rarely makes the cut outside of dedicated combo shells. Modern is similarly crowded — the bar for sorcery-speed removal is high, and six damage doesn't kill players.
