Abuna Acolyte

A repeatable damage-prevention valve attached to a tiny body, built around the idea that a cleric can keep soaking small hits turn after turn rather than blanking one big swing the way a one-shot prevention spell does. The first ability is the broad one: a tap to shave a single point off any target, enough to fog a lone attacker, turn off a one-toughness pinger, or keep a creature alive through a point of burn. The second narrows the target to artifact creatures and doubles the output, which tells you exactly what era of board this acolyte was built to police: a world thick with metal bodies where two prevented points is the difference between a trade and a survivor. That second mode is the more interesting design wrinkle, because it rewards a deck already invested in artifact creatures rather than just any white midrange shell, tying the card's relevance to its surroundings. The catch is the body it rides on. At 1/1 it dies to the same point of damage it would otherwise prevent, so an opponent answers the engine by ignoring it entirely and pointing removal at the acolyte before it ever taps. Prevention this small is also a tempo loser against decks that simply attack with more bodies than one tap can blunt. It is a grindy, attrition-minded piece: useful when the game slows to a crawl, invisible when it speeds up.
