I'm still messing around with sets and experimenting with these new megas and Pokemon.
Gliscor is fun to use acrobatics on because most people will guess toxic stall, but because of the lack of gems and Gliscor's natural stalling ability it might be better to go a different route.
I'm afraid I won't be able to do enough physical damage even with Barbaracle. If I can figure something better I might change Barbarcle, and depending on how Gardevoir's different sets play I might decide to run mega Mawile instead. I'm not too good at team building myself, though.
