I'm considering adding catcher (taking out a level ball or two). There are times when I really hate not having that in this deck.
I actually ran pokedex before I ran level ball and skyla (4 ether 4 pokedex 4 heatmor 48 energy). It wasn't the best card, but if I'm going to run more trainers, it might work. The biggest hassel with this deck is deciding how many trainers to run. You run too little, you lose consistency, but if you run too many, you're not going to be OHKOing EXs which is kind of the point of the deck. Pokedex allows you some control over what you discard with fiery licks. Even then, I'd want to run no less than 40 energy (45 being ideal).
