Shield Mare

A hatebear tuned against exactly one color, though only half its design admits it. The evasion clause reads red and nothing else: the Horse walks past red blockers and does nothing special against green or white ones. The life gain, by contrast, is color-blind and always-on. It fires on entry, so three life is banked the moment the body hits the table regardless of who is across from you, and it fires again every time an opponent's spell or ability picks it out as a target. That second trigger is the wall a burn deck runs into: every removal spell or targeted burn pointed at the 2/3 refunds three life to the caster's clock, turning the act of answering it into a loss of tempo. Against a red deck those two engines stack into a body that is genuinely miserable to race, evasive on offense and life-taxing on defense. Against everything else the evasion sits dormant while the life gain keeps working, so the card never fully idles; it just stops being pointed. That is the honest shape of a color-hate design: not a coin flip between all-star and vanilla, but a card whose upside scales with how much red sits in the opposing list. Read the room right and it is a wall you cannot burn through; read it wrong and it is still a 2/3 that gained you three and might gain you more.
