I've come up with my own type of deck, revolving mostly around Gourgeist and both of it's attacks, coupled with a Sinister Hand Dusknoir or a Hypnotoxic Laser. With just Gourgeist and Laser, it's got the ability to knock out absolutely anything in the game. If status effects are being blocked at the moment, all it'll take is two attacks anyway, to kill anything.
Gourgeist's first attack spreads damage around very fast for 1 psychic energy, being usually around 80 to 100 damage on the board. Two of those is usually enough damage on the field to knock out any EX, once Dusknoir is out on the field. It's also very disruptive, as I don't have to go for an EX, instead I can go for the smaller, easier to pick off targets, like small basics.
Second attack is where you really smash things around. With poison damage, even without Dusknoir or Virbank, it's an automatic OHKO. Even Sturdy pokemon aren't immune to it.
Add in a Darkrai (might take it out, honestly), some Super Rods, and you have a really good prize trade, and can take prizes before even attacking. Still tweaking it to it's maximum, but overall, I utterly love how the deck runs. I think Lysandre is going to be a bit of a problem, but then again, Catcher doesn't even do much to me. It pulls off lategame wins so unexpectedly.
