Wicker Warcrawler

An undersized price for an oversized body, with a self-destruct timer baked into its only line of text: each time it goes to war, it shrinks. The 6/6 frame is the bribe, and the -1/-1 counter at end of combat is the bill, payable whether the crawler attacks or blocks. That symmetry is the design's sharpest edge. Many fading creatures of this lineage punish only one side of the combat ledger; this one charges you for blocking too, so it cannot park itself as a free wall while it waits to swing. Six trips into combat and it counters itself out of existence, which means it arrives with a known shelf life the moment it resolves. The counters open a second wrinkle: any effect that moves, doubles, or feeds on -1/-1 counters finds a willing host here, and a creature that volunteers to accumulate them is rarer than its plain stat line suggests. As colorless artifact muscle, it slots into decks with no business fielding a 6/6 otherwise, which is precisely what the downside pays for. The honest read is a stopgap body for a deck that wants to apply pressure in the midgame and does not expect the game to last long enough for the timer to bite.
