>>53778588What do you want to use your deck for? As long as it's for casual games it should be okay-ish.
There are deckbuilding guides in the op, but some quick feedback:
-less energy, you can divide the amount by 2.
-more ways to search for mons, ultra balls are generally better than supporters like Jacq for that, since you can then use your supporter for the turn on something else.
-similarly you need ways to draw other than supporter, stuff like industious incisors Bibarel, refinement Kirlia, or radiant Greninja.
-have some disruption, stuff like boss's order, judge, Roxanne, etc.
-look out for synergies, pic related (add lake acuity to the list)
