Tough Claws does notably not affect Rock Slide/Stone Edge and Earthquake, which are some of the moves used most commonly by Physical attackers. This is especially important as 3 of the 6 fully-evolved Tough Claws users are Rock-types, which ordinarily love the EdgeQuake combo. Though I don't know how intentional that is, it does make Tough Claws a bit more interesting than an Ability that simply provides a 30% Special Attack boost.Blastoise/Mega Launcher: Mega Launcher makes sense, but in name only. I have no idea why Mega Launcher is a Pulse-powering up move. Already a "pulse" trait move is pretty niche. Aura Sphere ("Pulse Bomb" in Japanese) was originally a Signature Move for Lucario, Dark Pulse & Dragon Pulse exist only to be the default "strong" Dark & Dragon Special move when Gen IV did the Physical/Special Split, and Water Pulse I think was made to just be a mid-power Special Water-type move to fill in midlevel Move slots. Not to mention that, at the same time we got Mega Launcher, we also got Tough Claws. Tough Claws increases the Power of all Moves that make contact (aka most Physical Moves) to their opponent by 30%. Why wasn't Mega Launcher made a Special equivalent?
That being said, I am annoyed by the fact that they took a move that is generally restricted to rare Pokemon and legends and slapped it on two random aquatic creatures just because they had too few Pulse moves to play with otherwise.
