ok..I'm going to explain why uxie x is played. I'm not trying to be mean but you seem not to get it. Unown Q allows your pokemon to have 1 less retreat, which in uxie x's case, means FREE retreat, so let's say they kill spiritomb..ok. send up uxie with unkown q attached, level up into uxie x..and yay..now you can bring uxie x back so it Doesnt Die. Problem solved
Also..Attacking with palkia G isn't that good. you should get him benched ASAP.
Now..on to the rest of the list.
-2/2 noctowl (it's bad in so many reasons, mods I hope I don't have to explain in detail)
-3 Relicanth..Why is he in there? you Already have a Good main attacker..bit redundant. One as a tech MAYBE. but 3..thats not good.
-1 Azelf One is enough
-2 water energy palkia gx=don't attack with it
-4 Rainbow You're putting basic energy in, they dont dmg your pokemon
-3 candy if you only have one stage 2 its kinda pointless.
-4 handy uxie's better
