I don't really want to say where I'm going, and I think I'm going to play a G deck. But about Blissey, don't do it! By the time you get enough energies on a Blissey for it to be dangerous, your opponent could get all of their pixies set up or a Dusknoir that you can't hit without it coming back for major damage, etc. Once the first Blissey with 7 energy dies, what's left? You either have to waste Night Maintenance for the energies or attack for 40-60 damage before you get going again. Sure, with Boost Energy, Lunatone, Cessation Crystal, all that good stuff. But now?
