Split cards have two card faces on a single card. The characteristics of the half you didn't cast are ignored while the spell is on the stack.

A split card's characteristics are a combination of its two halves while it is not on the stack. For example, Cease // Desist has a mana value of 8 while it is in your library. If an effect allows you to search your library for a card with mana value 4 or less, you can't find Cease // Desist.

To cast a split card, choose one of its halves to cast. There's no way to cast both halves of any of the split cards featured in this set.
