I'm not sure how viable this is, but what do you guys think about a potential Greninja/Dusknoir/Gourgeist (XY) deck? For those that aren't aware, Gourgeist has an attack for 1 psychic energy that puts 2 damage counters on each of your opponents Pokemon, and then for 2 psychic reduces both the defending and it's own HP until they are both at only 10 HP remaining. I feel as though this provides an excellent opportunity for a lot of spread damage for Dusknoir to play around with, and will allow Greninja to get some KOs more easily, especially for Gourgeist's low cost first attack that can get up to 120 damage on the field while also bypassing Mr. Mime.
