Comments

You have two Scarfers and a Specs user, I would recommend putting Life Orb on one of them (Galvantula, probably).

I would also remove Frosmoth's Scarf and put Heavy-Duty Boots, as well as replacing Giga Drain or Air Slash with Quiver Dance. To go along with this, remove Ribombee's Quiver Dance and Bug Buzz in favor of Sticky Web and Stun Spore.

Replace Brick Break with Close Combat on Heracross.
