Suit Up

Because the 4/5 base overwrites rather than stacks, this swings in either direction. Point it at a small attacker and you have a real threat; point it at an oversized blocker and you have shrunk it into burn range or onto the fixed number of a removal spell. The Vehicle mode is the sharper trick: an uncrewed Vehicle is not a creature and slides past creature-only removal, so animating one into a 4/5 with no crew cost paid lets a Vehicle you never intended to activate suddenly attack or block. And the artifact typing that rides along does no combat work at all: it feeds static conditions like Metalcraft and Affinity, adding to a permanent count without adding a permanent, the quiet upside layered under a stat rewrite. None of these modes is loud. Three mana buys a temporary body-editor plus a replacement card, with the artifact tag underneath as a bonus for any shell wired to count artifacts. Read as a plain combat trick it is unremarkable; read as the seam between an artifact-count engine and a board that was flesh a moment earlier, it does something at instant speed that little else in blue can, and the cantrip keeps the attempt free of card cost.
