I still need to get the Shining Genesects, but this is a deck I've been wanting to build since Genesect was announced! I just put together a preliminary list, and I'm sure there's changes that can be made to it, but I do feel like it's a solid start. Zoroark GX is a nice partner in this deck that gives me a decent attacker to use against Volcanion and other Fire-types, as well as provide some draw support.
Pokémon - 17
3 Shining Genesect
3 Bulbasaur
1 Ivysaur
3 Venusaur
2 Zorua
2 Zoroark-GX
3 Tapu Lele-GX
Trainer Cards - 33
4 Professor Sycamore
4 N
3 Guzma
1 Brigette
1 Acerola (Not entirely sold on just one Acerola, but I also don't have room for a second one and feel like it's a clutch card.)
1 Skyla (This spot is flexible, but I do like the option of being able to grab a Rare Candy or another Item directly from the deck.)
4 Ultra Ball
1 Heavy Ball (Able to grab me an Ivysaur or Venusaur without having to discard cards from hand.)
3 Rare Candy
2 Field Blower
1 Super Rod (Thought about Rescue Stretcher but energy is important in this deck.)
3 Choice Band (Would rather have Fighting Fury Belt but Zoroark can't use them.)
2 Float Stone
3 Aether Paradise Conservation Area
Energy - 10
10 Grass Energy
