What Natures? I don't think Mega Charizard Y should be mixed, make it full special and dump Blast Burn for Fire Blast or Flamethrower. You waste EVs on four of your Pokemon. Swampert is too bulky for Sash, give it Leftovers instead. Iron Tail is hit-or-miss; if you're running mixed, go for Flash Cannon.

I’m not really very competitive so I don’t really pay attention to natures or Evs, Charizard’s thunder punch is for type coverage, but I could switch the rest of the moves to special and flash cannon for lucario is a good idea! Thanks for the help!
