Double Vision

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

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. The new targets must be legal.

A copy is created even if the spell that caused Double Vision's ability to trigger has been countered by the time that ability resolves. The copy resolves before the original spell.

You can't choose to pay any additional costs for the copy. However, effects based on any additional costs that were paid for the original spell are copied as though those same costs were paid for the copy too.
