It starts as a status move, so Prankster affects it. Then it turns into Tri Attack/whatever else in gen 6. Hopefully this makes more sense to you than it does to me!Does Nature Power count as a special attacking move? It's a status move that transforms into a special move, so does it still count?
Otherwise it seems like it would work great with Roserade and it's naturally high special attack.
