This is my main deck for Unlimited 100 card singleton using the 150 rules/banlist. If you're unsure of the rules see my post here on Pokegym at: http://pokegym.net/forums/showthread.php?t=163570 and a link to the Facebook page is in my sig. Hopefully you can help me with some tweaks, I know Dark Explorers is going to help A LOT!
EXs (B+W series) are banned and certain other cards are upgraded to ex status, which I've noted. I've left the specific set for most of the un-evolved Pokemon off as the choice generally doesn't matter too much and put a link to EVERY named card (0_0 oh god, that took a while) Here's the deck-list, strategy and card choices follow below:

ENERGY - 29

20 Dark Energy
3 Fighting Energy

The Honchkrow line has become my main attacker (it's my favourite Pokemon) as it provides discard which helps with this decks disruption theme. Mysterious treasures Honchkrow is one of my favorite card designs ever, if it has the energy to use its attacks, all my Murkrow can use them for free. This combos well with double rainbow well as the -10 damage won't apply to the Murkrow. They also have resistance to fighting which covers for my Tyranitars weaknesses.

Tyranitar is a huge tank of a Pokemon and their spread attacks put pressure on popular bench sitters like Claydol and Dark Dragonair. Speaking of Claydol, it's the draw engine this deck uses and there's no better option in Dark and it can use my splash of Fighting energy to maybe hit an Electric Pokemon for 80.

There's some excellent set-up Pokemon in Dark such as Sableye and Spiritomb. Ditto from Fossil scales with the powercreep of the game... it'll probably never be bad :P What ever broken Pokemon your opponent has, you get it as a basic, such a cool card! Anyway...

It's strengths are:
*almost mono-typed means reliable energy
*good spread and snipe options alongside strong direct attacks
*low energy usage through SF Tyranitar and MT Honchkrow
*lots of disruption
*few ex's

weaknesses:
*few strong, independant basics
*lack of energy acceleration (I plan on getting an exp. share for this)
*reliance on Claydol
*almost mono-typed means unlikely to hit for weakness
*no good "walls" or "safe guard"ers

Please comment and maybe even give the format a try! I have LackeyCCG and Skype if you want to give it a go.
