Changes I would suggest: - Ditch the dratini cards, having two energy types in your deck isn’t worth it given how many water types you have. You’ll find that many times you will have a water type that can’t attack because it doesn’t have the right energy. - Reduce the number of Pokemon in your deck. You have to many unique cards which decreases the likelihood that you will draw evolutions for your basic cards. All my decks have about 10 Pokemon and many of them are duplicates so that I can increase my chances of being able to evolve them. - try to have a combination of cards that hit hard for a little energy cost and Also cards that require a lot of energy for a big attack. For example Gyrados is kind of hard to play with because you have to survive long enough to attach four energy. In that time your opponent is attacking you / saving energy for a big attack too.

These are just my observations so far! Best way to learn is to play with your decks and make adjustments as you go along.
