Undead Slayer

Hatebears come in two shapes: the ones that tax everyone equally, and the ones that only matter if the opponent happened to bring the right deck. This is firmly the second kind, a repeatable exile aimed at exactly three creature types and inert against anything else. The targeting is what makes it worth examining: exile, not destruction, sidesteps the recursion loops that Skeletons, Vampires, and Zombies have always leaned on, the regeneration shields and graveyard-return tricks that make those tribes durable. Killing a Zombie that crawls back is no answer; removing it from the game entirely is. The activation keeps it honest in the other direction. Paying a white mana and tapping the creature itself per use means it clears one threat a turn at most, and committing the body to the ability leaves nothing back on defense. It is a designated answer card with a permanent on-board presence, an effect that once lived almost exclusively in reactive white decks built around a known opposing tribe. The undead-hunting Cleric is a recurring figure in white's vocabulary, a flavor-driven specialist whose entire reason for existing is the matchup it was printed to wreck. Against a field with no undead, that activated ability simply never fires, and the card sits there as a 2/2 with a dead button; against the right one, it becomes a slow, grinding lock on a third of the graveyard-centric world.
