Right now in D/P, my party currently consists of Dialga (lv 53 about), Golduck (lv 54 or 55), Honchkrow (lv 54), Uxie (lv 50, just caught), Machoke (lv 30 or so, but he's strictly used for HM's), and a level 20 Kricketune, which was the best Pokémon with a sleep-putting move (Sing) I had, I used him to capture Uxie. I will probably replace Kricketune with Azelf when I finally catch it. Reason as to why I'm so early in the game still with only 8 badges and no elite four victory is because I obtained the game three weeks ago.
