Nothing is set in stone. If you want to suggest a totally new Poke'mon, go for it. (I'm having second thoughts about Uxie after seeing how easily my friend's fell in battle.)
Metagross @ Life Orb
(Brave Nature, Clear Body)
Protect
Meteor Mash
Explosion
Earthquake
EVs: 252 Hp/252 Atk/4 Def
Uxie @ *insert item here*
(Impish Nature, Levitate)
U-Turn
Trick Room
Protect
*insert 4th move here*
EVs: 252 Hp/252 Def/4 SpDef
Open up with these two, letting Metagross protect itself for one turn from any nasty attacks, giving Uxie the chance to set up the trick room. After which, U-turn (Although not very powerful) can give Uxie a free chance to do a little damage and then switch someone else back into it's place. Protect might help Uxie in case Metagross needs to make a needed sacrifce with Explosion I suppose.
