Costume Closet

The counter-battery: instead of stapling a permanent boost to a creature that dies with it, this parcels out +1/+1 counters one at a time and reclaims value when the modified creature leaves. The sorcery-speed activation and the once-per-turn tap keep it from being a combat trick; you commit a counter during your main phase and accept that the buffed creature is now a target. But the trailing trigger is where the design earns its keep: any modified creature you control (whether the counter came from here, an Equipment, or an Aura) leaving the battlefield feeds a counter back onto the artifact. Removal that used to be pure tempo loss becomes partial refund, and the closet slowly refills its ammunition. That reframes how you sequence: dumping both starting counters early is not throwing them away if you have a plan to cycle those bodies, because the deaths reload the source. It rewards a board built around modification as a recurring theme rather than a single anointed threat, and it punishes an opponent's removal by converting each kill into stored value. The artifact itself never blocks, never attacks, and never dies to creature removal, which makes it a stubborn engine in the corner of the board that outlasts the creatures it is buffing.
