Sleep with the Fishes

Pacifism disarms; this locks, and then hands you a body for the trouble. Where the classic don't-untap Aura simply keeps a creature tapped, this one taxes the removal exchange by refunding the caster an evasive attacker: tap the threat on entry, and generate a one-power unblockable Fish that starts chipping in soon after. The Aura is a soft answer (it does not kill, and bounce or a blink undoes it), but the Fish token is permanent even after the enchanted creature breaks free, so the trade tilts toward the caster over time. That token clause carries more than it appears: one power of unblockable damage is negligible on its own but relevant to any strategy counting connections, whether that is a mill or drain payoff, an equipment carrier, or a saboteur trigger. Structurally the design descends from the long line of don't-untap Auras stretching back to early Sleep and Claustrophobia effects, but it folds the answer and the incremental clock into a single card rather than asking for two. The cost is the tempo hit: at four mana it is slower than a hard removal spell, and it leaves the biggest threat on the board rather than under it. What the extra mana buys is that you never fall behind on the board while you hold the line.
