Pyromancer Ascension

If the spell that’s copied has an X whose value was determined as it was cast (like Bonfire of the Damned does), the copy will have the same value of X.

If either of Pyromancer Ascension’s abilities triggers, it will go on the stack on top of the spell that caused it to trigger. The ability will resolve first. If it’s Pyromancer Ascension’s second ability that triggered, the copy it creates will also resolve before the original spell. The copy is created even if the original spell has been countered.

If the spell has damage divided as it was cast (like Fiery Justice does), the division can’t be changed (although the targets receiving that damage still can).

If the spell that’s copied is modal (that is, it says “Choose one —” or the like), the copy will have the same mode. A different mode cannot be chosen.

Pyromancer Ascension’s second ability can copy any instant or sorcery spell, not just one with targets.

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).
