Rollin' (Iron Treads/Geeta)

Would you consider adding Beach Court instead of Path to the Peak? Everytime you attack with Iron Treads you have to either attach an energy and pay the retreat cost or use one of the many switching cards you were forced to add. Since almost every pokémon in this list gets free retreat from the stadium, you could cut some switching cards and save up some space.

Also, I think you have way too many ways to fetch pokémon, I would cut the unreliable Capturing Aroma or at least some of them.

Some cool adds could also be Adaman (you don't have that many energies to burn, but it could come in clutch in many situations), Pokégear 3.0 (to get Geeta consistently, also you already have a ton of supporters), either Bravery Charm or Exp. Share, and Radiant Jirachi (helps with the setup, could be good to leave in the active after attacking with Treads)

I love your decks, keep them coming! :)

MrOwO I'm not sure about Beach Court, realistically you're only ever actually going to need to switch in the Lost Box matchup before they've built up Giratina (or if your opponent tries to stall you out and chooses not to attack) because pretty much any deck can start knocking out Diancie and Klefki on turn 2. Path can be massively detrimental to a lot of annoying decks, specifically Mew since it can turn off Klefki with Fusion Strike Energy (which most modern Mew lists are running in fear of Spiritomb (Paldea Evolved), I think) and otherwise doesn't really face any pressure to not just Psychic Leap itself back into the deck to avoid the 2HKO.

I see what you mean on Aroma, though. I was running it because I am the most unlucky person in the world and was struggling to consistently get Lumineon out with just Ultra Balls, but yeah I definitley think Pokegear is a good suggestion that would remedy that issue - I'll make the edit now lol.

Thanks for your help :]
