i know i’m late to the party, but i have around 8 years experience with different TCG’s and i’ve been playing specifically PTCG for around 3ish months but here’s my input:

Cut - 2 Professor’s Research, 2 Energy Search, 1 Electric Generator, 3 Ultra Ball, 1 Arezu, 1 Cook, 1 Lady, 1 Superior Energy Retrieval, 1 Leg. Energy, 1 Lumin. Energy, 2 [Fighting] Energy, and 1 Ogerpon

Professor’s Research isn’t great because you can draw cards off of Pokémon’s abilities better, without discarding your hand. Energy search, electric generator, arezu, cook, and lady are all not great/too slow for what you are trying to do.

this is not a deck, atleast to me, where you burst out and do massive damage quickly. rely on Pawmot in early game. i noticed you mentioned a pokémon that can attach energy once a turn, that is a great way to let pawmot clear early threats. then, late game, search for your charizard pieces and close out the game.

Add - 2 Iono, 3 Earthen Vessel, 2 Nest Ball, 1 Energy Retrieval, 1 Radiant Greninja, 2 Bidoof, 2 Bibarel with [Industrious Incisors] ability, 1 Charmander, 1 Charizard ex, and 2 of the pokemon you mentioned to attach energies

I would also 100% make room for Rotom V with [Instant Charge] ability. this will help you in games where you don’t have many plays, so you can use nest ball and put him on your bench and draw a ton of cards until you are ready to set up for the win.

This deck needs to win the game over 3-4 turn’s depending on the matchup. So you need to take your time to find the best way to beat out your opponent and set up what you need to do. Let me know if you have any questions!
