Any feedback would be appreciated. This is my first competitive team in a very long time. I would like to keep the two Mega Evolutions available. I was wanting to put M-Charizard Y over M-Gengar but I really like the use of Hex with Prankster Thundurus & Will-O from Rotom. I was thinking about cutting some of the SpA EVs on Chandelure to make up for its frailty. So if someone could help me with EVs that would be awesome. The last time I played the VG competitively was back during GSC on the GBA.
