Push // Pull

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.

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.

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.
