A team for the elite 4

If you guys want a good team to defeat the elite four or a gym leader here's a good team.
You're gonna need a dark or ghost type to defeat Caitlin so here's a good list of Pokemon.
a lampent (or a chandelure if you have one) at least level 45
OR a cofagrigus at least level 47

OK that was to defeat Catlin now to defeat Shauntal you're gonna need a water/dark Pokemon here's some good Pokemon choices.
maybe a deino (or zwelious if you have one but I doubt it) at least level 43
OR you might want to use carracosta or seismitoad at least level 40

Now onto Marshal he's a bit easier (my opinion) you're gonna need some flying or psychic types.
You can use an unfeazent or a braiviary but if you have Pokemon black you can use mandibuzz at least level 42
OR you can use these psychic types. You can use a reuniclus if you have Pokemon white or gothitelle if you have Pokemon black.

Last but not least, Grimsley. he's got dark type Pokemon so your gonna need fighting or bug types.
Maybe use a meinfoo (or a meinshao if you have one)
OR your emboar ( if you chose it at the start)
If you don't have any of those or the next Pokemon GET SOME!!!
So here's the bug Pokemon.
Use a larvesta at least level 38 or a scolipede or a galvantula.

But most important of all BRING SOME REVIVES! Otherwise you'll fail and never win.
