Interesting list, though i have a few concerns. As someone who plays unlimited to farm tokens though, i think you should have had a list that didnt have Tropical Beach, and then put that card as a tech. Just that one card costs more than the rest of the deck combined and you want two of them. Same goes for the HGSS cards as many who hold them online are naturally reluctant to trade them for current packs.
As for the meta, You should point out that Trevanent/Wobbuffets is picking up in popularity due to Trevenant Break. It is meant to counter not only the Shiftry decks, but your anti-shiftry variants. You will auto lose because they will get a Trev by Turn 2
That said a unique article that i would not expect to see on Pokebeach and for that i applaud you guys
