Rules

From the Comprehensive Rules (June 7, 2024—Modern Horizons 3)

• 702.40. Storm
  • 702.40a Storm is a triggered ability that functions on the stack. “Storm” means “When you cast this spell, copy it for each other spell that was cast before it this turn. If the spell has any targets, you may choose new targets for any of the copies.”
  • 702.40b If a spell has multiple instances of storm, each triggers separately.

Rulings

• The storm copies are put directly onto the stack—they aren't played. That means the copies don't generate storm copies themselves, and they aren't counted by other storm spells played later during the turn.
• Each storm spell with a target allows you to change the target for each copy of that spell. You make that choice for each copy individually.
• When counting spells played in a turn, you do count spells that were played face down, spells played from zones other than a hand, and spells that were countered.
• A copy of a spell can be countered, just like any other spell, but each copy has to be countered individually. Countering a storm spell won't counter the copies of it.
• Removing a card from the game using suspend doesn't count as playing a spell; you only play a suspended spell when you remove the last time counter from it and that ability resolves.
• When a spell like Twincast copies a spell that has storm, the copied spell's storm ability doesn't trigger. You get just one new spell.

Storm scale

Mark Rosewater has declared that he doesn’t ever see Storm coming back in a Standard-legal set. On Blogatog, he uses the"Storm scale" - a scale of 1 through 10 where 10 is Storm - when he answers questions about the likelyhood of the return of a mechanic. 1= will definitely see again, 10 = never say never, but this is pretty close to never. Despite this, Storm cards have been re-printed in supplemental sets such as the first Modern Masters and the Magic Online-only set Vintage Masters.
