I REALLY hope that by Pulse moves Mega Launcher doesn't JUST mean Water Pulse, Dark Pulse, Dragon Pulse, etc. If that's true, then that's a bunch of BS if you ask me, seeing as how it has access to both Hydro Pump and Surf that are both powerful Water-type moves on their own. Besides, the only Pulse move Blastoise can learn IIRC is Water Pulse. That doesn't make much sense. I think there will be a list of moves that are considered "Pulse" boosted as X5Dragon stated. There's just no way the ability could be that trash on a Mega Pokemon.
