Teferi's Puzzle Box

A symmetry trap dressed as a wheel. The effect looks egalitarian: at the start of each draw step, every player swaps their hand for an equal count of fresh cards, replacing exactly what they held. But the count is the trap. The Box draws you cards equal to the number you put on the bottom, so the value scales with how full your hand is. Sit on a fat grip of unplayed answers and you exchange all of it for an entirely new draw, a churning lottery that can spin into your gas (or away from it). The sequencing carries more weight than the symmetry suggests: the turn-based draw resolves first, so a player who empties their hand each turn still draws their one card, then immediately bottoms that single card and draws a fresh one. Nobody opts out; the floor is a one-card reshuffle, the ceiling a full-hand churn. This inverts the usual logic of card advantage. Hoarding stops being safe storage and becomes a turn-by-turn reshuffle, while a board-first deck that dumps its hand pays only the smallest tax. It also scrubs information clean each turn, so any plan built on knowing what an opponent is holding gets erased on a clock. Where red wheel effects fire once on cast and draw everyone a full grip, this recurs automatically and indefinitely, turning the draw step into a standing rule change that must be answered or accepted. That recurrence is the whole point: not a burst of cards, but a permanent that rewrites how every hand behaves until someone removes it.
