Zero, seriously, my deck was GOOD. I admit that my deck needs some change but still. Even if it has a lot of strategies and a lot of 1-1 pokemon line, it is still really good. The advandage of it is that depending on what you start and what your opponent has, you can plan a strategy to counter it. I, once again, admit that in the beginning of a game, I have exactly nothing in my head. But, mostly after 2-3 turns, I already have an strategy to distroy my opponent deck. Maybe you are going to say:"Oh, your opponent will already be prepared, you won t have time." In the first turn, I will take something to counter and win time and then, after a few turns, full strategy. Even if I start with a really sucky hands, I don t care because all my pokemon can use cheap one energy attack. Then, I will just take good things that helps my strategy. (I ditched the giratina lock combo, which, as you said, was too slow. I have a paralyse deck now, kind of)
Anyway, you can do a Locking deck with Mewtwo lv.X plus Areodactly Base plus Vileplume that blocks trainers and finally with Areodactly that can enable all pokebody on your turn. True, it will be a little pain VS luxchomp but with the trainer lock, so...
