High Priest of Penance
A removal engine disguised as a 1/1, and the trick is that its threat scales with whatever gets thrown at it. The body is a deterrent in reverse: an opponent cannot send an attacker into it without gambling a permanent, because any combat damage arms the destroy trigger. The sequencing matters here and is easy to get backwards. Lethal damage does not let the effect happen while the cleric is still around; the damage triggers the ability, then state-based actions bury the 1/1 before the trigger resolves. But the trigger has already gone on the stack, so the destroy still fires: you trade the body and take one nonland permanent with you. The wrinkle that separates it from ordinary deathtouch deterrence is the targeting. Deathtouch only punishes attackers and only kills what it fights; a single point of damage dealt to this cleric becomes a destroy effect you aim wherever you like, including at a planeswalker or an artifact well away from combat. The catch is the body itself. Any damage at all is lethal to a 1/1, so feeding it a ping of your own is a one-shot trade, not a loop, unless you keep it alive with indestructible or a toughness boost first. That conditionality is the cost: without a reliable way to hit it on your terms, it is a fragile speed bump that politely asks the opponent to do something foolish, sitting in the small, sharp tradition of permanents that weaponize being struck.
