I haven't played much lately because I've been waiting for Pokebank, but now that it's (sort of) here, I figured I'd get back into the swing of things. I threw together a really rough team and laddered on PS for a while tonight. I bred a perfect Bold Unaware Clefable to use a super annoying Minimize / Calm Mind / Moonlight / Moonblast set a while ago, but I wasn't sure what else I wanted to use with it and wanted to try things out. Laddered with the aforementioned Clefable, CB Talonflame, Occa mixed Aegislash for Talonflame and Charizard, Life Orb Will-O-Wisp Gengar for Mega Kangaskhan, Rocky Helmet Rotom-W, and SD Lum Bisharp. Hit #2 on the PS ladder, so I feel comfortable breeding the stuff I can get before Pokebank now and then use it in my game.
Mainly posting to hype the SHIT out of that Clefable set and the Gengar set. Both of them put in an assload of work for me. Clefable just straight up counters most sweepers, including Blaziken (not that I don't have it covered with Talonflame), Dragonite, Cloyster, Azumarill, and more, and sets up alongside them just for them to find out later that they can't do shit to me, even at +6. Gengar is perfect for handling Mega Kangaskhan because so few run Crunch, and even the ones that do will still get burned. It also just hits stupidly hard with Life Orb Shadow Ball, Sludge Bomb, and Focus Blast, and hits everything at least neutrally.
Anyways, yeah, those are really cool mons that I recommend trying when you can. :)
