I originally wanted this team to be around a Dread Plate + Krookodile, with Knock Off and Pursuit. I decided to add Florges to check Hydreigon. I have Chesnaught to get rid of water types. Aerodactyl-Mega to be a quick, fast-type which can outspeed most things. I have Chandelure to take out most physical walls, I orignally had Galvantula to Sticky Web fast things, but I decided to go for a backup sweeper in Suicune and a mixed wall just in case Krookodile fainted.

Comments

Krookodile: Life orb is better than dread plate because it powers up more and powers up everything.
Chesnaught: It doesn't need special attack, so replace serious with careful. Leech seed wears off when the target switches (which is what happens when you use roar), so replace it with seed bomb.
Aerodactyl: Ice fang doesn't cover any weaknesses, so replace it with earthquake.

Krookodile is one of the few mons where Black Glasses/Dread Plate is viable, because it's main job is to pursuit trap and it doesn't need LO to do that, just the dread boost.
You could also replace Wing Attack with Aqua Tail to cover Rhyp.
