you have enough revives and fullrestores but you need to get your Pokemon up a few more levels or you'll keep dying to the fourth of the e4 and the champion, also make sure you have at least 1 dark or ghost move for the 4th guy as he uses psychic personally i would go for another Pokemon with fire but that's your choice.
My lineup for the Elite Four in Platinum is: Staraptor-Lv.90 Heatran-Lv.90 Empoleon-Lv.95 Dialga-Lv.90 Palkia-Lv.90 Giratina-Lv.90 With those Pokemon it is easy but it should also be easy with any Pokemon around these sort of levels. Don't forget to take revives and full-restores just incase.
Garaa
You cannot buy max revives at any shop. You just have to go look for them in poke balls.
you must have blastoise then you have a pidgeot then a dragonite then must have moltres the have a wigglytuff level 67 must know ice beam then finally you must have a jolteon these Pokemon are the best to use to beat the elite four plus the champion aslo don't you dare forget to have max revives and full restores
it is possible if your Pokemon are strong enough though i would recommend using potions and revives it's alot easier!
You could easily beat the champion, Cynthia. About half your party will be knocked out, but if you can kill the Garchomp, you can for sure beat her. She has a spiritomb, a gastrodon, a milotic, a garchomp,and a lucario.
Have a lot of revives proteins irons and full restores because your team sucks
use your full restores or revives
id have to know your levels and stats before anyone could tell you but it sounds like a pretty good team but until we know the stuff i listed i couldn't telly ou if its capable of standing a chance agaisnt the elite four. when i did i used a lv. 65 torterra lv 55 mespirt lv. 41 tentacool, lv. 41 machoke, lv. 40 rapidash, and lv.40 staraptor but i only used the first 2 bc of all my full restores and revives. u need about 15 revives and 15 full restores to get to the champion at least and give one poemon a razor calw if u got one.
Yo dude when i beat it I had a weavile level 50, floatzel level 50, gallade level 50, honchkrow level 50, drapion level 50, infernape level 60(sixty) I think you may be all right with a bunch of revives, ethers, full restores, and GOOD MOVES
At least level 40, it should be possible with correct type matching and lots of revives/full revives/full restores.
train your Pokemon hard and long you will eventually win plus bring revives and full restores.
Those Pokemon are a strong team, covering most, if not all, weaknesses (depending on their moves). If they are all at roughly level 45 and you have enough potions, revives etc you should be fine.
level them up to about 60,70 or 80 then you shoud you may want to take some revives etc
Probably if you bring a lot of revives and full restores.
they need to be all atleast lvl 52 and up with 10 full restores and 5 revives
it can but you need a few revives and full restores
