Team stronger?

Give them items and make them all around the same tevel - this will make battling more fun

Train them more like mine:(Your moves are fine)
Blaziken Lv.78
Zapdos Lv.60
Lanturn Lv.67
Dialga Lv.63
Uxie Lv.89
Cresselia Lv.95

And for me, the only kind of moves I ever use at high lvls like this are strong offensive or realy devistating moves, id have some attacks that I have a lot of usage for like 15-25 uses and some more like 5-10 uses. I go all offensive. O and it doesnt always help to stick with one type of move for a pokemon. Like all fire or all water, I would throw in something else, you did pretty good on this though. Unless you keep losing or something I wouldnt worry about it too much.

Motilic The Atrract Try To Change To Hydro Cannon. Give X Defend X Attack X Special And Others.. Like Dragon Scale.. I Have Metal Coat Like Protein Hp Up And Many Others

Choose one of them and go to the elite four and battle with it till it is about to faint or already fainted and then get the next one you want to train. The first one you should get to level 100 is Infernape. Next do Dialga or Palkia. Then Garchomp because a level 100 Garchomp is nearly invincible. I used my friends one and beat the whole elite four without healing and he still had about 100 hp left.
