You need way more type coverage, Bud. I know that UU is full of mediocre Grass Bug, and Normal-types, but that doesn't mean that Ghost, Fighting, and Fire-types won't be popping up there.
I see where you're going with these sets: The first two support each other while sweeping at the same time, then the next two is Beat Up + Justified, and the last two is a two-person synergy; one purely supports, the other purely sweeps.
I find the strategy a little static, meaning that if one thing goes wrong, you've basically screwed your strategy. Not to mention your plain vulnerability to a dedicated Water-type or fellow levitators.
I'm sure you'll be on your toes about that stuff, and with that said, it's a very solid team. It just looks very...focussed on one spot, if that makes sense.
