Pokemon Analysis
I'd add in another gastly just so you can ensure that you can possibly get 2 set up during the game. (This is because of the pokemon catcher threat.)  I would like to see another Mr. Mime in the deck, just in case one is prized, and you can easily get rid of a mime jr to make room for it.  The more babies in a deck, the more I worry about losing the game due to being donked.

Energy Analysis
I might add in a rescue energy or two, just to be able to reuse your gengar or mew without using a revive.

Trainer/Supporter Analysis
I'd try and find room for 4 junk arm and 2-3 pokemon catcher (great for stalling while you snipe or work on their hand).  Maxing out your seeker to 4 is going to be essential for getting those pokemon into their hand to put them into the lost zone.  To make room for this, I think you can reduce your juniper and judge.  If you still need room, you can reduce your energy to 7-8 psychic (no rescue). 

Overall
This deck is pretty close to what I would consider perfect.  The biggest flaw with this deck is that it's slow, so it tends to struggle in tournaments, especially in top cut.  But overall I think it's a great deck and has a lot of potential.
