If you cast the first half of a split card with aftermath during your turn, you’ll have priority immediately after it resolves. You can cast the half with aftermath from your graveyard before any player can take any other action if it’s legal for you to do so.

If another effect allows you to cast a split card with aftermath from any zone other than a graveyard, you can’t cast the half with aftermath.

If another effect allows you to cast a split card with aftermath from a graveyard, you may cast either half. If you cast the half that has aftermath, you’ll exile the card if it would leave the stack.

While not on the stack, the characteristics of a split card are the combination of its two halves. For example, Destined // Lead is a green and black card, it is both an instant card and a sorcery card, and its mana value is 6. This means that if an effect allows you to cast a card with mana value 2 from your hand, you can’t cast Destined. This is a change from the previous rules for split cards.
