Don't forget about Cresselia. Despitie Moonlight getting trolled, it gets plenty of support moves. Helping Hand can be great. You use Helping hand while your partner uses Earthquake, which misses Cress thanks to levitate, and just hits both opponents for boosted damage. Dual Screens will support very well. Ice Beam/Icy Wind can be used to take down opposing flying-types. And it's got Thunder Wave as well. Trick Room could also be a big one. If your opponent uses Trick Room, or Tailwind, this will put you back on top as far as speed goes. I would reccommend Cresselia > Aerodactyl. Also I don't really like Cradily, I don't feel it hits hard enough for VGC play. Walls don't exist in VGC because of how offensive it is. Not even Blissey can keep itself alive indefinitely. 2 Pokémon attacking at once is overwhelming. Most of the time when Cradily is used, it's to wall the opponent thanks to Sandstorm, and set up Curse for a sweep. In VGC I really think it has 0 merit. The only useful attack I think it gets is Rock Slide, but it will be too slow to utilize the double flinch.
Also, ubers in VGC are mostly the super power Pokémon or Pokémon exclusive to an event, so you don't have to worry about stuff like Garchomp and Excadrill being uber. Just things like Mewtwo, Kyogre, etc. or event Pokémon like Jirachi or Celebi.
