Whenever you cast an instant or sorcery spell with the chosen name, you may copy it. You may choose new targets for the copy.

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

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

If the spell being copied has an X whose value was determined as it was cast (like Skeletal Scrying has), the copy will have the same value of X.

Effects based on any additional costs that were paid for the original spell will be copied as though those same costs were paid for the copy. For example, if a player exiles three cards from their graveyard to cast Skeletal Scrying, and you copy it, the copy will also cause you to draw three cards and lose 3 life (but you won't exile any cards from your graveyard).
