No I seriously mean everyone and their sister uses Lucario. And as for Gliscor... I would think along the lines of jolly nature for more speed but less SpA.
And as for your Golem Esp... you may want a Baton Passer or something so that you can switch Golem in with a little help. I suggest Ninjask. Have it hold the Focus Sash, with Agility, Swords Dance, Baton Pass, and Protect. Ev it for speed and Hp i suppose. It is ideal that you send out Ninjask 1st because of possible entry hazards. With protect and the focus sash, you are guaranteed at least three turns to prep for the coming Golem.
