1. Weather

Sun teams are really common these days. VGC is all about hyper offensive instead of stall, so you'll see sun more than rain teams. Pretty much if you see Charizard, assume sun team.

2. Mega Kangaskhan

This thing terrorizes everything. That chance to double attack is really overpowered, especially with the strategy below.

3. Swagguard!

Just pair a Meowstic/Klefki with a Mega Kangaskhan, use Safeguard with Meowstic/Klefki and then Protect/Fake Out with Mega Kanga. After that, just keep having your Meowstic/Klefki use Swagger on Mega Kangaskhan; it won't get confused because of the Safeguard.

4. Trick Room

Not as common as it was in Gen 5, but you do see common Trick Room users such as Reuniclus, Aromatisse, and sometimes Trevenant.

5. Dark Void Smeargle

Cheap, cheap, cheap! I would support Spore on Smeargle, but not Dark Void. Oddly enough though, I haven't seen too many Smeargles; probably because of Mega Kanga being a good counter.

This is so laidback and slightly opinionated I can't even half take you seriously.

You forgot Double Team/Minimize. Minimize Blissey Psych Up Gothitelle is the sole reason I like not not play VGC rules.

Dave you should have consulted me before doing this!!!

Mega Kangaskhan...

Don't know too much about VGC, but M. Kang and Charizard Y are suuuupper common on wifi. Both are really annoying. Charizard more than Kang, IMO.

Edit: Nvm. Kang under SwagGuard, or any Pokemon with immense priority, is a big pain. But then again, a Heat Wave from a Chariard Y is also annoying. Bleh. WHY DON'T PEOPLE USE OTHER POKEMON! C'mon! I battle using a Mightyena! Be different!
