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.
Far // Away
You can choose the same object as the target of each half of a fused split spell, if appropriate.
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.
