Hey
@Lord Goomy!
I'm interested in your deck idea and I think I have a few ideas that will hopefully improve it. Here they are:
Ultra Space (FBL): I've noticed that some of the above comments have been about using Nest Ball to search out most of your Pokémon (excluding Kartana GX of course). Though you have Mysterious Treasure to help out with Goomys and Solgaleo Prism Star, Ultra Space (FBL) allows you to consistently retrieve your Kartana GX from your deck. This also adds the bonus effect of always having a way to bump opposing Stadiums whether they are beneficial to your opponent or harmful to you.
Fighting Fury Belt (BKP): My biggest fear if I were playing this deck would be if my opponent had a way to constantly OHKO my Kartana GX's. While the energy denial effect of the deck nullifies most of that, Fighting Fury Belt (or you could use Metal Frying Pan (FBL), your choice) adds another layer of disruption your opponent has to find a way to get out of (making it even harder for them to take K.O.s). In the rare case, you could also attach it to Goomy to increase its HP cap if necessary.
Oranguru (ULP): This will help against any opposing stall decks you'd come across and gives you a way to recycle Energy disruption such as Crushing Hammer and Plumeria. It isn't needed of course, but having an out to recycle resources is always something this deck could benefit from.
Oranguru (SUM): Moving on to the other Oranguru, this one is definitely something the deck can benefit from as I believe it would be hard for this deck to maintain the lead throughout the entire game with your main attacker constantly being shuffled back into the deck. While N can benefit you, N can also really cripple you if you aren't prepared and draw into a clunky hand.
Beast Ring (FBL): Personally, I prefer this over Max Elixir for just one reason: Max Elixir isn't guaranteed, and when you play only three of them and only 7 Metal Energy, you will most likely miss most of them. Beast Ring is a guaranteed option, the one downside of it is that you can only play it when your opponent has 3 or 4 prize cards left. The great news is that you as the disruption deck can actually
control how many prize cards your opponent takes. What this means is that you can intentionally allow your opponent to K.O. a GX/EX (Tapu Lele Gx for example) and then remove all of their energy on the field afterwards. Once you do, you can just play Beast Rings as you draw into them and constantly N your opponent down to a 3 or 4 card hand for even further disruption.
Alright, with some of what I've mentioned in mind, here is a revised list (including some stuff I didn't mention):
