Mirrormind Crown

Token doublers redirect creation; this one hijacks it. Most anthem-style token payoffs (Doubling Season, Anointed Procession, Parallel Lives) multiply whatever you were already making, keeping the token's identity intact. This inverts the exchange: instead of getting more of the token you intended, you get copies of the equipped creature, and only the first batch each turn is converted. That "instead" is the whole trick, turning any token-generating engine into a photocopier for a single body of your choosing. A one-off Saproling maker becomes a way to stamp out extra copies of a payoff creature; a go-wide engine gets narrowed to a stack of whatever wears the Crown. The once-per-turn limit and the replacement structure keep it from spiraling: you have to assemble both a source of tokens and a creature worth cloning, and you pay two more to move the Crown if the target dies. The design's cleverest wrinkle is that it decouples the two halves of a combo, letting the token-maker and the thing-to-copy live in separate parts of the deck and meet only when the Equipment is attached. Copying as an Equipment effect is a genuinely odd frame; most cloning lives on creatures or enchantments, and putting it on a movable, re-targetable piece of gear means the "what am I copying" question gets answered fresh every time the Crown changes hands.
