Much in the spirit of my Palkia build is the third – and probably strongest – of the lists: the turbo build. This has been floating around for a while, and I know of several people who've advanced the techiness beyond this basic version; however, this should help get you started.
(Tuuuuuurbo! Too bad Gengar isn't on this box art.)
Pokemon (22):
4 Gastly SF
2 Haunter SF
1 Haunter TM
4 Gengar Prime
4 Unown R LA
3 Uxie LA
1 Azelf LA
1 Spiritomb AR
1 Spiritomb TM
1 Unown Q MD
Trainers/Stadiums/Supporters (31):
4 Junk Arm
4 Poke Drawer+
4 Pokedex Handy 910s
4 Pokemon Collector
3 Seeker
3 Broken Time-Space
2 Lost World
2 Pokemon Communication
2 Luxury Ball
2 VS Seeker
1 Rare Candy
Energy (7):
7 Psychic
[NOTE: the energy should likely be increased to at least 8 or 9 – I feel uneasy with this count at the moment. Palmer's might also be an appropriate "8th energy"]
[NOTE: Mesprit and Mr. Mime would both be interesting, and maybe even necessary additions to the list.]
Advantage/s: The list is obviously fast. Through Poke Drawer, Dex, Unown R's, and Junk Arm to bind them all together, pulling out a first or second turn Gengar Prime suddenly gets a lot easier. Although running only three Seeker seems suspect in a turbo list that requires Seeker to be played over and over again, Junk Arm helps alleviate this by means of VS Seeker, ultimately giving you a maximum of _nine_ uses.
Disadvantage/s: with nineteen trainers and zero Bebe's, one could say that this deck is heavily vulnerable to Spiritomb Arceus locks. However, this shouldn't be too big of a problem, as the number one most popular Spiritomb deck, Vilegar, should be a very comfortable win for you.
