Fury Storm

If you have multiple commanders, you’ll copy this spell for each time you’ve cast either of them. For example, if you’ve cast one commander once and one twice, you’ll copy this spell three times.

Fury Storm can 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 (like Lavalanche does), the copy will have the same value of X.

Each Storm’s triggered ability can copy the Storm spell even if that spell is countered before that ability resolves.

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, but not how many targets there are. 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).

Each Storm’s triggered ability counts only how many times you’ve cast your commander from the command zone before that triggered ability resolves. If you cast your commander again later, you won’t get another copy.
