Fab 4

Hello, noobie here! I've been in Pokémon from 2008ish to 2010, then a bit of 2012, then some 2013 and to now. I've had Blastoise in this deck since I started again back in 2013, but I've always been making changes. It was originally Blastoise Seismitoad, and that was bad, so I've always kept making changes, and I think this might be the final need of change. So, enough BS, here it is!

Looks pretty solid. Only thing I might suggest is to maybe work in an Energy switch or two but that's just my preference at the moment.
