Keeper of the Cadence

Graveyard hate that answers three of the game's most recursion-heavy card types, wrapped in a body that survives long enough to keep answering. The activation carries no tap cost, so the card fires as often as you have mana to spend: not a one-and-done exile spell but a persistent tax on any engine that leans on rebuying an artifact, a flashback spell, or a key sorcery from the yard. The bottom-of-library clause is the tell. It never removes a card permanently the way exile-based hate does, a deliberately gentler answer, but the trade is worth naming: repeatability, plus a target the opponent cannot easily play around, since a card placed on the bottom of a sizeable deck is functionally gone for the game even though it technically still exists. Note the restriction: creatures are off-limits, so this does nothing to slow a reanimator plan built on returning bodies. Its lane is artifact recursion and spell-based engines, the decks that treat their graveyard as a reusable spell library. The 2/5 frame does quiet work too: five toughness parks it above most early combat and cheap removal, keeping the activation online across a long grind rather than trading off before it earns value. This is interactive answer-as-creature design, asking nothing of the board and everything of the graveyard, a slow drip rather than a hard stop.
