The reason I gave Lucario an Adrenaline Orb is because I battled my friends and they ALWAYS use Salamence, Arcanine or Mawile so the speed boost would be really helpful. I'm not going to change the Pokemon so just moveset changes, but items can change too. Clefable has 0 speed Evs so that's it can work with Slowking in Trick Room. Thanks!

EDIT: Changed Clefable's Flamethrower and Thunder Wave to Reflect and Light Screen. Also given it light clay. Given Chandelure a Choice Scarf to boost speed.
