Storm King's Thunder

Storm King's Thunder will create copies of the spell that caused its delayed triggered ability to trigger even if that spell has been countered by the time that ability resolves.

When the delayed triggered ability of Storm King's Thunder resolves, it creates X copies of a spell. You control each of the copies. Those copies are created on the stack, so they're not "cast." Abilities that trigger when a player casts a spell won't trigger. The copies will then resolve like normal spells, after players get a chance to cast spells and activate abilities.

If the spell Storm King's Thunder's ability copies is modal (that is, it has a bulleted list of choices), the copies will have the same mode(s). You can't choose different ones.
