If you cast a split card with fuse from your hand without paying its mana cost, you can choose to use its fuse ability and cast both halves without paying their mana costs.

Some split cards with fuse have two halves that are both multicolored. That card is multicolored no matter which half is cast, or if both halves are cast. It's also multicolored while not on the stack.

If you're casting a split card with fuse from any zone other than your hand, you can't cast both halves. You'll only be able to cast one half or the other.

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.

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 you cast both halves of this spell fused, the targeted creatures will be dealt 4 damage first and then be phased out, even if they had less than 4 toughness. Any abilities that trigger based on those creatures being dealt damage will trigger.
