Luxchomp is still winning the most, Gyarados is 2nd, Vilegar is 3rd. The rest include, Machamp builds, Sable/chenlock, Dialgachomp and a lot of sparse random decks, Some regigigas. Honestly just check out the "Whats winning Citites '10-'11" thread, you'll get a nice idea. As for triumphant, it single-handedly made Gyarados tier 1 again with Junk arm and rescue energy. Rescue energy has made its way into a lot deck, especially Vilegar, as you get to abuse Fainting Spell and it still returns to your hand after the flip. Gengar prime has proven itself as a tech in Vilegar increasing it's match up against Gyarados. Twins has made its way to almost being a staple in any decks that require a starter (Ie, Sableye, Smeargle, Spiritomb) Blackbelt is probably better in Regigigas than any other deck, I think it's too awkward. For the 3rd question, We don't really know what we are getting in the next set other than some Japanese Promos, and Reprints of card we already have/had. I would go ahead and buy a Triumphant box, it's got a lot going for it. It has a good ratio on the amount of primes and the amount of usable primes your bound to get something decent. Unless your me and pull 2 electrode prime, at that point your kind of screwed.
