Catch // Release

Some split cards with fuse have two monocolor halves of different colors. If such a card is cast as a fused split spell, the resulting spell is multicolored. If only one half is cast, the spell is the color of that half. While not on the stack, such a card is multicolored.

On the stack, a split spell that hasn’t been fused has only that half’s characteristics and mana value. The other half is treated as though it didn’t exist.

If a player names a card, the player may name either half of a split card, but not both. A split card has the chosen name if one of its two names matches the chosen name.

To resolve Release, the active player chooses a permanent they control for each of the listed types, then each other player in turn order does the same, then all the chosen permanents are sacrificed simultaneously.

If you control an artifact creature, a nonartifact creature, and no other artifacts or creatures, you must sacrifice both permanents. You must choose the artifact creature as the artifact and the nonartifact creature as the creature. The same is true for any combination of types—you sacrifice a number of permanents as close to five as possible.

To cast a fused split spell, pay both of its mana costs. While the spell is on the stack, its mana value is the total amount of mana in both costs.
