Bonus Round

Bonus Round’s ability will copy any instant or sorcery spell, not just one with targets.

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.

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

The copy will have the same targets as the spell it’s copying unless its controller chooses new ones. That player may change any number of the targets, including all of them or none of them. The new targets must be legal.
