Good item for story mode Lucario

I have an item on all my other pokemon except Lucario and i would like to have an item on it so does anyone have an recommendations and could you tell me where they are. Thanks

What moveset do you use?

I dont really know yet it’s a Rash nature with Aura Sphere extreme speed and close combat and calm mind im tossing up physical or special lucario

Probably a Life Orb (and maybe you want to make it your Mega when 1.2 comes out)

Okay i put a life orb on it, and my mega is Delta Charizard currently but maybe il just rotate my mega once the Lucarionite is released
