Okay, I think I got the feel to this deck: (its a) Metronome Deck, as in steal the opponents pokemon features.
First of all, I think that the Scyther, Electabuzz, Super Energy Removal, Item Finder, Energy Retrieval, Full Heal, Plus Power, and the Electric Energies should be removed. That leaves room for 26 cards total. I think I'll set aside those Energies for later...
Clefairy, and Clefable are an important aspect to this deck, So I would add 2 more Clefairy and another Clefable. I would also add 2 Chansey and 4 Ditto's; which I think go with this deck quite nicely. I think that actually the Mr.Mime card shall be fine with just 2 cards, and I probably shouldn't, but I think the Damage-Swap deck would also be a fine twist on the deck.
Firstly, add another Bill. I think maybe only 2 Gust of Wind are needed. Another Energy Removal. I believe the goal of this deck isn't to directly to attack the opponent with these powerful moves, so I think I'll take out some Defenders. I think I'll trade those Scoop Ups with Mr. Fuji's and add two, to pick up those greatly-damaged Chansey. And I want to add a Pokemon Breeder and 2 Pokemon Trader.
Okay, gonna pick up those energies now. So I think 15 Psychic Energies shall be enough, and add another Double Colorless Energy.
