Storm

Storm is a keyword ability on instants and sorceries that creates a copy of the spell for each spell played before it in the current turn.

The first cards with Storm were printed in Scourge, with more being printed in Time Spiral.

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.
