Weathered Sentinels
A Wall that punishes attackers by becoming one itself, and the trick is entirely in the conditional grant. Defender keeps it home most of the time, but the middle line rewrites who it may hit: anyone who swung at you last turn is a legal target, so the more aggressive your opponents get, the more openings this thing gets to swing back. When it does attack, the +3/+3 and indestructible turn a passive 2/5 into a 5/8 trampling body that can crash through a blocker without dying in the exchange. Those bonuses last until end of turn, though, so they are a purely offensive package: by the time an opponent's counterattack arrives, the creature is back to a 2/5, and it is vigilance (not the pump) that lets it stand back on defense. Reach and vigilance round out a defensive profile that never forces a choice between guarding and threatening. The design logic is deterrence made literal: a blocker that costs opponents nothing to leave alone, until they take a swing at you, at which point their aggression becomes a standing invitation to hit them back. It reads as a Wall and plays as a slow revenge engine, most alive at a table where several players are trading blows and each attack against you quietly arms the next counterpunch.
