Ulrich's Kindred

A creature that costs one color to cast and a different color to activate is an unusual shape, and the design leans into it: the body asks nothing of your manabase beyond red, while the protection mode is gated behind a green cost you pay only if your fixing reaches it. That lets the card slot into a mono-red or Boros shell as a plain trampler with no concession, and rewards a Wolves build that can produce green with a mode that keeps an attacker alive through a block. The target line is what narrows it into a combat tool rather than a general safety net: the ability only touches an attacking Wolf or Werewolf, so you fire it during declare-blockers, before combat damage, to answer the ways a swinger dies in the red zone (a double-block, a fight effect, a destroy-based removal spell aimed at the attacker). Because it names an attacking creature only, it does nothing against a sweeper resolved on your opponent's own main phase, when your board is home and idle, and indestructible is blank against edicts and sacrifice effects that route around destruction entirely. That keeps it a tribal lord's bodyguard, not a flexible protection spell. It sits in an odd spot among Wolf-and-Werewolf payoffs: charging one color to cast, demanding two colors of support to unlock, and rewarding commitment to the creature type without taxing the decks that cannot reach green.
