At the very least, Heracross does not demand Trick Room to make good use of that Megahorn to sweep. Or care about Burn. That makes him superior outside of Trick Room for offensive purposes in my mind. However....I would think a mixture of Support/Offense on the KnightBug would work wonders. It has really good Defenses, and KnockOff/Megahorn/Pursuit/Filler.
