Thornwatch Scarecrow

An artifact creature that asks which colors you've surrounded it with, then rewrites its combat math to match. Scarecrows of this era were colorless connective tissue: bodies that earned relevance by reading the board rather than carrying static text of their own. This one keys off the green-white hybrid axis it was printed beside, granting itself wither next to a green creature and vigilance next to a white one, so a Selesnya shell turns it into both halves at once: a 4/4 that swings without leaving you open and stamps every blocker with permanent -1/-1 counters instead of damage that resets at end of turn. The logic is that a six-mana 4/4 is dull on rate alone, so the conditional grants pay you for building toward a color pair rather than splashing the body as filler. Wither is the aggressive half, converting combat into attrition by shrinking blockers for good and trading up against anything that survives the swing; vigilance is the defensive counterweight, letting the Scarecrow guard the ground while still threatening to attack. It represents a colorless design that fishes for color identity to justify its cost, rewarding a focused board without ever locking the artifact to a single color outright.
