Feral Appetite
Graveyard hate is usually pure disruption: you spend mana to shrink an opponent's recursion and get nothing back but the denial. Here that transaction is inverted. The activated ability keeps the disruptive function, exiling a card from any yard, but attaches a reward to hitting creature cards specifically, spinning off a 1/1 Pest each time it strips one. The result is a hate piece that grows an army out of the very graveyards it dismantles, and because each Pest returns a life when it dies, the tokens feed a slow-burn aristocrats loop rather than sitting around as chump blockers. The static half is what ties the two functions together: attacking Pests get the buff and deathtouch, so every token the exile ability manufactures becomes a two-power removal-on-a-stick attacker the moment it swings. That converts a defensive activated ability into an offensive one over time, which is the tension worth naming: you pay repeatedly to grind an opponent's yard, and each payment builds a board that wants to attack. The Pest type is narrow support, so this reads as a color-pinned engine for a token-and-graveyard build rather than a generically splashable answer. Its ceiling is set by how many creature cards are sitting in graveyards to eat, which makes it a payoff that scales with the graveyard density around it.
