I heard many say Decidueye variant is unplayable post-rotation, mainly beacuse of losing forest of giant plant. But Gardevoir and Metagross, 2 of the best decks post-rotation are stage 2 too. So i don't see why not. Here's a list i am working on:
Pokemon x20
4-3-4 Decidueye GX
2-2 Ninetales GX
1 Tapu koko
1 Espeon EX
1 Oranguru
2 Tapu Lele GX
Supporters x14
4 Sycamore
4 N
1 Skyla
1 Brigette
2 Guzma
2 Acerola
Items x18
4 Ultra ball
3 Rare candy
2 Choice band
3 Float stone
2 Max potion
1 Revitalizer
1 Rescue Stretcher
2 Field blower
Energy x8
4 DCE
4 Grass energy
