6/7/2013 Spells cast from zones other than a player’s hand and spells that were countered are counted by the storm ability.
6/7/2013 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.
6/7/2013 The 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.
