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.

Each split card has two names. If an effect instructs you to choose a card name, you may choose one of those names, but not both.

If an effect allows you to cast a spell with certain characteristics, consider only the characteristics of the half you're casting. For example, if an effect allows you to cast an instant or sorcery spell with mana value 2 or less from among cards in your graveyard, you could cast Cease this way, but not Desist.

Each split card is a single card. For example, if you discard a split card, you've discarded one card, not two. If an effect counts the number of instant and sorcery cards in your graveyard, Cease // Desist counts once, not twice.
