For my Lucario
heres the moveset:
And can you give me a strong steel type move
Replace Work Up for Nasty Plot, then use Dragon Pulse. Nasty Plot boosts Sp. Atk to +2, so your other moves do more damage. I would recommend swtching Flash Cannon for Dark Pulse, better coverage, and Aura Sphere hits most types hard.
Well, Earthquake would be the better choice to cover its Fire weakness. However, if your Lucario has better Special Attack, go with Dragon Pulse. Protect is pretty useless unless it's a staller, which Lucario isn't.
That depends on your stats. Protect usually ISN'T the best choice for Lucario (Lucario's designed for sweeping.)
