@Glaceon: For the Deck that you are playing, Gyarados is obviously the Metagame in the DC Metro area, with a side of SP, Vilepluff, and Vilegar. So Anything with blaziken would be terrible. Anything with Luxray would be fantastic. So IMO you should play Luxchomp with a Dialga tech if you seriously want to win.
And actually games are often decided by reversal flips. If they weren't, people wouldn't play it.
IMO gyarados with a Lux tech isnt that good. unless your area has trainer lock heavily played, its not worth it. And even then you are sacrificing cards that could otherwise could be used for setting up faster and it's very hard to get Lux out with trainer lock on. I often see the bright look coming because they don't want to waste a warp energy on the Gyara so they wait till it dies, and I can easily prepare for that by using seeker, or preparing a warp energy. It's just not worth it. Play luxchomp, it's better. And if you are dead set on gyarados play reversal. It's unpredictable, and easy.
And you have so many better cards than me. I'm struggling just to make 2 decks, and I share cards with my brother.
