Oran Berry for Recovery
Life Orb for extra damage - If you go with Life Orb, give it an HP IV of 0-9 and no EV investment in HP.
Okay honestly? Don't use it. Axew, Scraggy and Dratini are all better at Dragon Dancing thanks to better bulk, speed and higher attack. If you really want to, Eviolite is probably necessary because of Bagon's atrocious defenses.
