Catch // Release

A Threaten effect and a symmetrical Edict, married by Fuse so that the steal and the sacrifice run back to back on a single resolution. Cast alone, each half is a known quantity: the blue-red Catch is a temporary theft that untaps and grants haste, the red-white Release is a Diabolic-Edict-style tax that forces every player to give up an artifact, a creature, an enchantment, a land, and a planeswalker, their own choice. Fused, the two clauses resolve sequentially as one spell, which is where the wrinkle lives. Catch resolves first, so by the time Release asks each player to sacrifice, you are the one who controls the borrowed permanent. You cannot attack with it between the two halves (a spell's resolution offers no priority and no combat step), but you can feed it to your own side of the symmetrical sacrifice, turning what should have been a returned creature into permanent removal while sparing one of your own permanents of that type. The structural cleverness is that Release is per-permanent-type and controller's-choice, so it never cleanly answers one thing; it bills the whole table evenly, and the steal is what lets you pay your share with someone else's card. That timing puzzle is the entire point. This sits at the far end of Fuse's design ambition: not two efficient spells sharing real estate, but two effects whose interaction across one resolution is the reason to pay the full nine.
