Does a copy of a spell on the stack count as being cast for storm purposes?

Storm (CR 702.40) works by counting the number of spells cast before the storm spell this turn, then creating that many copies of the storm spell. The copies are placed directly onto the stack — they are not cast. CR 702.40b explicitly states that the copies are created on the stack and are not cast.

Because the copies are never cast, they do not count toward the storm count for any subsequent storm spell played later in the same turn. CR 706.10 confirms that when a copy of a spell is created on the stack, it is put there without being cast, so no 'cast' event occurs.

Additionally, because storm triggers off the act of casting a spell (CR 702.40a: 'When you cast this spell…'), the copies themselves do not re-trigger storm — only the original spell being cast triggers storm.

Concrete example: You cast Grapeshot when five other spells have been cast this turn. Storm triggers, creating five copies of Grapeshot on the stack. Those five copies are not cast, so if you then cast another storm spell afterward, your storm count is still 6 (the five earlier spells plus the original Grapeshot), not 11.

In summary: only spells that are actually cast (CR 601.2) count toward storm. Copies generated by storm or any other copy effect do not count, because they bypass the casting process entirely.
