4 rulings from Wizards of the Coast
- 8 December 2022The copies 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.
- 8 December 2022The triggered ability that creates the copies can itself be countered by anything that can counter a triggered ability. If it is countered, no copies will be put onto the stack.
- 8 December 2022A 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.
- 8 December 2022Spells cast from zones other than a player's hand and spells that were countered are counted by the storm ability.
