no, the elite four have like lv 60+ Pokemon. the garchomp could kill all your Pokemon in one shot. its lv 66.
Torterra, Gastrodon (any type), lucario, bronzong, rapidash, and Staraptor. have this team and you will become unbeatable (my team).
I used these: Tentacruel, Lucario, Torterra, Staraptor, Luxray and Infernape. I recommend getting all of your Pokemon into a high level, like in the 55-70s. Also, make the types a variety and also study the elite 4's Pokemon. Also practice. Get many strategies.
it depends on their attacts
It will be......... luxary or staraptor... and a strongest non legendary dragon Pokemon in sinnoh is Garchomp!!!!
Your first priority should be evolving your level 61 gligar into a gliscor. Then, I think that you need a ghost and/or ice type. You see, you have two flying types in staraptor and gligar. I would drop staraptor as its defence is weak. I would take a Gengar perhaps. But, you can still beat the Pokemon league and champion with this team :)
you should use if starting with infernape you should use infernape luxaray gyrados dialga staraptor if staring with empoleon you should use empoleon dialga garchomp staraptor drapion and luxaray and starting with torterra torterra staraptor dewgong lucario dialga and drapion
Use Torterra, Staraptor, Lucario, and Dragonite. Keep in mind that you will have to have more pokemon. Always try to have as many double-types as possible. you should use dragonite you should use dragonite there all good but i think you should go with snorlax Snorlax definitly, since he's got a huge defence and a lot of HP, plus he learns Giga Impact and Hyper Beam.
a staraptor,torterra,garchomp,luxray,milotic,and a floatzel
My party is: Lucario lv. 50 Luxray lv 49 Palkia lv 50 Dialga lv 49 Torterra lv 48 Staraptor lv 45
Floatzel Snorlax Heracross Roserade Staraptor Empoleon/Torterra/Infernape
your team is good just don`t 2 of the same type Pokemon on the same team ( ha i should be talking i have like 3 water types
Remove Ralts and Buizel, get yourself a Magmortar if you can or a similar Fire-type.
