ITT: We figure out how to fix some of the worse Mega-Evos.

I'll start. M-Ampharos.

Ability is now Surge Surfer. Also, when a Pokemon with this ability uses Electric Terrain it lasts for 8 turns instead of 5 (a Damp Rock parallel)

Electric Terrain also now makes it so Electric Attacks cannot Miss.

This will allow M-Ampharos to use Charge Beam and get a much needed speed boost, allowing it to finally sweep with its rather limited movepool.
