Tormod's Crypt

The original zero-cost answer to a graveyard, and the template every dedicated grave-hate piece since has been measured against. The design logic is brutal in its economy: it asks for no mana to deploy and no mana to crack, which means the only cost is the deck slot you spend including it. That pricing is the whole point. Against a deck that does not care about its graveyard, it is a dead draw you paid zero to keep; against one that does, it deletes the resource at instant speed, on your terms, in response to the trigger that was about to matter. The friction lives entirely in the activation: it taps and sacrifices, so it is a one-shot answer, not a recurring lock, and a deck that rebuilds its yard can play around a single Crypt. Wizards has spent decades printing variations that trade that clean rate for upside (Relic of Progenitus draws a card when it goes, Soul-Guide Lantern replaces itself, Nihil Spellbomb folds card advantage into the same exile) but none has retired the original, because none matches the pure zero-cost compression. When you want the cheapest possible insurance against reanimator, dredge, flashback, and delve, this is still the bar. It does one thing, asks for nothing up front, and the reason it has survived since the early days is that the math on "free, until you need it" has never stopped working.
