I've been testing this list for a while now, and I think it's pretty good. It's not quite perfect yet, and that's where you all come in. 
On to the deck:
Pokemon: 25
4-3-2/1-1 Gengar (SF-TM-Prime/AR16-AR)
1-1 Honchkrow (SV-SV)
1-1 Breloom (SV-SV)
1 Mr. Mime (CL)
1 Spiritomb (TM )
4 Smeargle (UD)
1 Unown Q (MD)
2 Uxie (LA)
1 Azelf (LA)
TSS: 24
2 Rare Candy (UL)
1 Luxury Ball (SF)
4 Bebe's Search (RR)
4 Seeker (TM )
3 Twins (TM )
3 Pokemon Collector (GS)
4 Broken Time-Space (PL)
3 Lost World (CL)
Energy: 11
3 Rescue Energy (TM )
8 Psychic Energy
Strategy: The typical LostGar strategy, get up Gengar prime, begin sending Pokemon from your opponent's hand to the Lost Zone, using techs such as Spiritomb and Mr. Mime to make better use of each Hurl Into Darkness. After getting 6 Pokemon in the Lost Zone, drop a Lost World and win. Gengar AR is for doing some actual damage while being able to switch back to Gengar Prime to send knocked-out Pokemon to the Lost Zone. Gengar Lv. X gets rid of the opponent's Lv. X's, as well as gaining some HP, Honchkrow is a tech that I use against Gyarados, and Breloom is for Dark-types like Tyranitar and Umbreon who can take a huge chunk out of Gengar; not only does it do nice damage due to weakness, it also discards Special Darks and Double Colorless. In the case of Tyranitar, it gives me a nice boost in that it won't quite knock it out, giving me the ability to knock it out with Gengar Prime (Or AR if it has Expert Belt) and get 3 Pokemon in the Lost Zone, as well as a prize card (Or two if it has Expert Belt).
With this list I can, relatively consistently, get a Gengar Prime out with a Psychic Energy T2 if I go first or T1 if I go second. After that, it's all about setting up the techs that I need and properly using my Seekers.
Thanks for reading, everyone. And thanks in advance for the help, edits, and advice.
