I'd like to second what @Zamrock said. Basically, Volcanion is a hard hitting nuke (although it has trouble getting past certain defensive mons) with a decent typing and good bulk. 70 speed is terrible though, because it limits its options greatly (scarf is too slow). The SR weakness isn't helping either, since it wants to switch in and out a lot to use its bulk/fire a nuke and it doesn't have a reliable recovery move, making it hard to keep Volc healthy. I loved using it at first, but tbh I find Keldeo better now at the same things. On Meye: I still believe this thing shouldn't get a suspect. Sure, it does extremely well vs defensive mon, but it's really easy to pressure with a more offensive team to the point where it can't switch in anymore. 20 base speed is horrible, meaning it'll always have to take a hit before it can click Recover. Fairies/Fires are very prominent in the current meta and are great checks to MEye.
