You know, I think you might consider dropping 1 Mime and the Shedinja as well as a fighting energy and going 3-3 Venomoth for the next test version of this deck. That way you'd potentially have 3 separate Venomoths to hide behind during a game, each one acting as a set-up for a max-ed out Pester. There would less of a risk of your opponent simply drawing all their prizes off your buffers IMO if you were able to consistently set up Pester to do 80, because then you'd be taking down their big attackers faster and more consistently while they would be KOing less of your fall-guys, leaving Gliscor lv. X to take care of whatever they had left in the mid to late game without really needing to hit-and-run as much.
Most decks tend to run 3 Warp Points max, and even then that is fairly rare (it's usually 1 or 2), so against something like this that is doling out special conditions left and right, your opponent is going to have to time those really well. That means that I doubt they would use them up just to get Venomoth out of the active spot in an attempt to avoid being hit with its Body, which helps to further ensure that they do end up attacking it and getting poisoned and put to sleep, setting you up for Pester. The cool thing about this Body is that the conditions it places remain (at least the poison, anyway) for you to exploit with Pester during your next turn no matter what, because obviously your opponent can't retreat, evolve, Warp etc. in between turns.
I like Shedinja's ability to hurt swarmers, but the fact that it needs to be KOed to do anything at all, plus the fact that Resent is a Power that can be shut off, plus the fact that Resent does not help Pester/inflict status effects, plus the fact that in the absence of any other Pokemon to hit with Resent, dealing 40 in exchange for a prize really isn't that great of a trade-off, all cause me to think it might lead this deck into the sort of consistency problems Burninating_Torchic was talking about. I know that if you hit for 60 with Gliscor lv. X and run to Shedinja and it gets KOed, activating Resent, you can come in and get a KO on pretty much anything by doing another 60, but the whole exchange thing is what kind of concerns me, especially since with only 2 Shedinja you're only going to be doing that once or twice in a game. Venomoth has a bit more HP and a decent resistance, so it isn't QUITE as easy to OHKO (like against Kingdra, for instance) which means you won't always be making an exchange so soon, and when you do exchange you'd have gotten the benefit of its Body twice. Plus, you're hitting them with a lingering poison and the slight chance that they'll miss both of the sleep flips before their turn and remain immobilized.
