wotc14 Jul 2017
Swarm Intelligence can copy the spell even if it’s countered before Swarm Intelligence’s triggered ability resolves.
wotc14 Jul 2017
If the spell that’s copied has an X whose value was determined as it was cast (like Torment of Hailfire does), the copy will have the same value of X.
wotc14 Jul 2017
The controller of a copy can’t choose to pay any alternative or additional costs for the copy. However, effects based on any alternative or additional costs that were paid for the original spell are copied as though those same costs were paid for the copy.
wotc14 Jul 2017
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).
wotc14 Jul 2017
Swarm Intelligence can copy any instant or sorcery spell, not just one with targets.
wotc14 Jul 2017
If the spell has damage divided as it was cast (like Chandra’s Pyrohelix), the division can’t be changed (although the targets receiving that damage still can).
