Whispering Madness
Wheel effects have always been a high-roll gamble: you refill your own hand, but you refill everyone else's too, and the symmetry is the price you pay for the velocity. Cipher rewrites the tempo of that trade. Encode this on an evading creature, and every time it lands combat damage you get the option to spin the wheel again for free, converting a one-shot reset into a recurring lever that turns on your schedule. The trigger is optional (the creature's controller chooses whether to cast the copy), so the repetition is a choice, not a compulsion: you fire it on the turn the math favors you and hold it when it does not. The wrinkle is in how the draw is sized: each player draws back equal to the largest hand anyone dumped, so a player hoarding a fistful of cards effectively sets the refill rate for the room. Cracking a nearly empty grip gives you almost nothing; cracking a player sitting on a full hand hands everyone a fresh stack, which is its own weapon if your deck converts raw velocity into pressure faster than the opponents can. The symmetry never fully breaks, which is the discipline holding it in check, but controlling when the combat damage lands means controlling when the wheel spins. Most cipher cards were marginal effects that needed the free recast to justify their existence; this one took a sledgehammer and made it swing again on demand.
