Depose // Deploy

If the target creature is an illegal target by the time Depose tries to resolve, the spell doesn't resolve. You don't draw a card. If the target is legal but not tapped (most likely because it was already tapped), you do draw a card.

You create Thopters and gain life all while Deploy is resolving. Nothing can happen between the two, and no player may choose to take actions.

If you copy a spell that's half of a split card, the copy copies that same half. For example, if you copy Assault, the copy is also Assault, not Battery.

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 sorcery cards in your graveyard, Assault // Battery 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 a sorcery spell with mana value 2 or less from among cards in your graveyard, you could cast Assault this way, but not Battery.

To cast a split card, choose one of its halves to cast. There's no way to cast both halves of this split card.

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, Assault // Battery has a mana value of 5 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 Assault // Battery.

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.
