Two things. One, Aero, I already have a Sableye. Pick something else, please? Two, I'm currently training for the Lavaridge gym battle and my team is Shirinui the Slakoth (level 13), Miku the Swellow (level 23), Batl the Machop (level 15), Cyrus the Kirlia (level 26), Hark the Gulpin (18), and an egg that I think becomes a Wynaut.
In my PC I have Kaito the Ninjask (level 22), Gumi the Grovyle (level 24), Maelstrom the Torkoal (level 16), Ikaru the Electrike (level 21), Mashew the Sableye (level 23), and Scarlet the Aron (level 24). Mael, I plan on leveling Torkoal more after the gym.
