Blastoise for pokemon champions

Hi, I want some help building a VGC team with Mega Blastoise in it. I know he isn't that strong in VGC, or at least there are plenty of better options, but he is my favorite Pokémon and I really want to use him.

I was thinking about using Mega Blastoise alongside Pelipper, but most of the teams I find on Showdown use things like Archaludon, Tailwind, etc. So most of the time, my Blastoise gets deleted before I can even make a move.
