Display of Power

If a spell has damage divided as it was put onto the stack, the division can't be changed, although the targets receiving that damage still can. The same is true of spells that distribute counters to targets.

If a spell that's copied has an X whose value was determined as it was cast, the copy has the same value of X.

If you cast Display of Power, you can, at most, make one copy of each instant and sorcery spell on the stack. It's not possible for one Display of Power to copy the same spell multiple times.

If a spell that's copied is modal (that is, it says "Choose one —" or the like), the copy will have the same mode or modes. You can't choose different ones.

If you copy multiple spells with Display of Power, you can put the copies on the stack in any order.

The copies will have the same targets as the spells they're copying unless you choose new ones. You may change any number of the targets, including all of them or none of them. The new targets must be legal. If, for any target, you can't choose a new legal target, then it remains unchanged (even if the current target is illegal).
