Can someone please help me pick out budget standards deck that does not have tapu lele I heard greninja and volcanion are good but cannot find any deck list
Glad to hear Greninja is a deck you are considering! When it comes to post-rotation deck lists, there won't be any out there for any deck really, because the season just started a couple days ago. After a couple regionals we will all have a good idea what the meta will look like, and of course the deck lists that go with it. As a result of this, the only good post rotation deck lists for a deck will be the ones people have tested out in PTCGO, at locals, etc. Here is my Greninja deck list that I have personally had a lot of success with on PTCGO, and at my own locals. Whether you choose to straight up play it or make your own changes, I recommend you at least consider using it as a starting place.
Pokémon: 19
3 Froakie- BREAKPoint
4 Frogadier- BREAKPoint
4 Greninja- BREAKPoint
4 Greninja BREAK- BREAKPoint
4 Talonflame- Steam Siege
Trainers: 31
3 Choice Band- Guardians Rising
2 Field Blower- Guardians Rising
2 Max Potion- Guardians Rising
4 N- Fates Collide
4 Professor Sycamore- BREAKPoint
2 Rescue Stretcher- Guardians Rising
4 Ultra Ball- Sun and Moon
3 Guzma- Burning Shadows
1 Super Rod- BREAKthrough
2 Fisherman- BREAKthrough
1 Professor's Letter- BREAKthrough
3 Evosoda- Generations
Energy: 10
2 Splash energy- BREAKPoint
8 Water Energy- All Sets
Good luck, and feel free to ask me any questions about any of the deck's functions
