Updated my post, and here's the result:
You know, for everything my team went through in one day (such as hax and being cleaned off by a...Focus Sash Aerodactyl), I'm sure proud of it for managing to hold itself in the metagame. This team is also the first time I've seriously considered using Slowbro as a support Pokemon, although it's not my Dark Horse to boast about.
Most of my losses are due to carelessness and apathy towards the game (I have other stuff to look at during battles), so I'm not entirely sure of potential weaknesses in my team. Anybody that can identify weaknesses will have my thanks.
