Depose

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.
