Just popping in to say that the base power limit for Pokémon with -ate abilities should be 69 base power, not 63. Here's why:
63 * 1.3 (-ate boost) = 81.9. Less than the normal base power limit of 90.
69* 1.3 (-ate boost) = 89.7. The closest possible to the normal base power limit of 90 without going over. If you don't care about going over very slightly, you could change the limit to 70 base power, which results in a base power of 91 after the boost.
Also, are we gonna just replace Mega Heracross's ability with Swarm so it can be unbanned, like FTR!'s thread was in the process of suggesting?
