I'd like to see Seviper be updated to be able to learn Gunk Shot, since for some reason it's not able to do so in AllGen. It's Mega Form should also have a different ability; Strong Jaw is great for a physical attacker, but if you're running Seviper as a special attacker, then it gets no mileage whatsoever from its ability. Its ability should be useful for both forms. Perhaps it could be changed to Corrosion?
