Tormod's Crypt

In Commander, Tormod's Crypt earns its slot as the cheapest reliable graveyard answer in the format — zero mana means it never competes with your curve, and the one-shot exile is wide enough to disrupt reanimator, dredge, or recursion loops at a table with no warning. In competitive Commander especially, the combination of free cast and artifact synergies with Urza and Jhoira shells makes it a mainstay rather than a concession to the meta. In Legacy and Vintage, Tormod's Crypt sees sideboard play against Dredge and similar strategies, though Relic of Progenitus often edges it out when drawing a card matters. In Modern and Pioneer, it competes with a crowded field of graveyard hate, but zero mana still buys it spots where speed is the only thing that matters. Pauper runs it freely — common printing, no cost, proven effect.
