Vedalken Outlander

Hatebears made literal: a creature whose entire job is to be unkillable by one color and to attack into it with impunity. Protection from red on a 2/2 body means burn cannot point at it, red blockers cannot trade, and any combat damage a red source deals it is prevented outright. The design is unapologetically narrow: against any deck without red, it is a vanilla two-mana white-blue 2/2 with no upside, which is precisely the point. This is a hoser tuned to a single predator, the answer to a metagame leaning hard on cheap red damage. Protection's four-part shield (no damage, no enchanting or equipping, no blocking, no targeting from the named source) does all of that at once, which is why a plain keyword printed on an otherwise blank creature reads as a wall against one color rather than a fair body. The artifact type line is a quiet second layer, letting the card slot into an artifact-matters shell or feed effects that care about artifacts while it does its anti-red work, though it offers no shelter from color-based removal: the white-blue cost is fully on the table. Everything about this body hinges on how much red sits across from it, and it was built to make that a deckbuilding question worth answering before the game starts rather than a topdeck you hope for.
