Ral, Crackling Wit

A copy of a spell can be countered like any other spell, but it must be countered individually. Countering a spell with storm won't affect the copies.

If a spell has multiple instances of storm, each will trigger separately.

Ral's first ability resolves before the spell that caused it to trigger. It resolves even if that spell is countered.

Spells cast from zones other than a player's hand and spells that were countered or otherwise failed to resolve are counted by the storm ability.

The copies of instant and sorcery spells you cast created by the storm ability are put directly onto the stack. They aren't cast and won't be counted by other spells with storm cast later in the turn.
