Whoa, whoa, whoa! Waaaay too many cards here. You should really cut deck size down to 40 unless you've got some kind of heavy deck-thinners like gadgets or Thunder Dragons. Second, Pot of Greed is banned according to the list, so that shouldn't be in there. Third, your cards are all over the place and your 'theme' is far too vague. Focus on doing a single thing and doing it well. For Darkness and Dragon combo, it would probably be Cyberdark monsters + Dragons, the archetype of which was posted
here. A lot of your cards are extremely situational Think of it as probability, how high is the chance of you getting both Red Eyes B. Chick, and Red Eyes Black Dragon when you have 55 cards in your deck? Furthermore, what are the odds of it surviving long enough for you to draw into Darkness Dragon (which will otherwise become a dead draw)? Let me answer that for you: it's not very likely. Also, Master Kyonshee is a pointless monster (Wimpy Zombie with no special ability and subpar stats) which is completely overshadowed by Ryu Kokki (If you were thinking of pulling it out with Pyramid Turtle). Dark Magician is a complete slap-on and really isn't doing anything for you (For two tributes you could get far better) and Fear from the Dark and Despair from the dark are pointless and situational because, let's face it, Darkworld does this so much better. Plus, discarding isn't too popular because of the afforementioned set of cards so those will most likely be clogging your hand, same for Regenerating Mummy.
Furthermore, zombies rely largely on special summons, so running Vanity's Fiend is just plain silly because it completely screws their powers over. Really, what were you thinking with that? Bone Tower is also pointless because it is not only very vulnerable to attack, but the deck thinning it provides is liable to help your opponent gather up a graveyard of tribute fodder for Game Overdragon or to be removed by Phoenix Blade for a Dimension Fusion or Return with which to wipe you out. Vampire Genesis with only one Vampire Lord is also a waste, plain and simple. Again, overly situational and just a dead draw most of the time. Vampire Lady isn't too appealing either since it's so frail that even Hydrogeddon will run it over and - as mentioned before - a lot of the machocist decks nowadays actually
enjoy having their cards discarded.
So, just at a glance I'd say drop these:
-1 Vampire Genesis
-1 Vampire Lady
-1 Dark Magician
-1 Master Kyonshee
-1 Double Coston
-1 Vanity's Fiend
-1 Soul-absorbing Bone Tower
-1 Fear From the Dark
-1 Despair From the Dark
-1 Giant Rat (Not really worth having a recruiter for the recruiter, especially since monster removal is all the rage)
-1 Swarm of Scarabs (ain't gonna' survive to get its effect)
-1 Dark Blade
-1 Pot of Greed (Say no to banned cards)
-1 Reload (-1 cards in hand is not very appealing)
-2 Luster Dragon
-1 Trap Hole
-1 Magical Mallet (Again, -1 cards isn't worth it unless you have a killer combo to fish for)
-1 Poison of the Old Man (This isn't a burn deck :\)
-1 Call of the Mummy (not enough Zombies to warrant it)
-1 Autonomous Action Unit (Too expensive >.<)
-1 Hammer Shot (More like Smashing Ground, please, you've got high-Atk monsters who'll just turn this card against you)
-1 Monster Recovery (Again, not really a worthwhile trade-off since you lose field presence)
-1 Soul Reversal (WTF? You don't even
have flip monsters <.<)
And those would be the dead weight. 25 cards in all, so now we're down to 30. Furthermore, zombies and dragons don't really play well together, so I'd suggest dropping the zombies for cyberdark monsters (to stay true to your vague 'theme'). So, cutting out the remaining zombies and their support cards:
-1 Vampire Lord
-1 Ryu Kokki
-2 Pyramid Turtle
-2 Book of Life
-1 Creature Swap
-1 Spirit Reaper
Now reduced to 22. Finally, just cutting out the cards that don't play well with Cyberdark:
-1 Compulsory Evacuation Device (This isn't really a bounce strategy)
-1 Raigeki Break (No real prospect of providing discard fodder)
-1 Zombyra the Dark
-1 Pitch Black Warwolf
-1 Ordeal of a Traveler
-1 Seven Tools of the Bandit
-1 Robbin' Goblin (A bit too risky)
-1 Red Eyes Black Chick
-1 Red Eyes Black Dragon
-1 Red Eyes Darkness Dragon
Now then, to fill up the open slots:
+2 Cyberdark Horn
+1 Cyberdark Edge
+1 Twin-headed Behemoth
+3 Masked Dragon
+1 Armed Dragon Level 3
+1 Armed Dragon Level 5
+2 Armed Dragon Level 7
+1 Future Fusion (Yay dumping =D)
+1 Dragon's Mirror
+1 Five-headed Dragon
+1 Mirror Force/Widespread Ruin
+1 Mystical Space Typhoon
+1 Stamping Destruction
+1 Card Destruction
+2 Smashing Ground
+2 Enemy Controller
+1 Sangan
+1 D.D. Warrior Lady
+3 Cyber Dragon
+1 Torrential Tribute
+1 Snatch Steal
+1 Ring of Destruction
Whew, I think that's the best I can do with this thing. So yeah, basically it's a major makeover but it should be an improvement. That should be four cards unless I miscounted somewhere. :3 So basically, the gist of this deck is to dump a load of dragons in your graveyard which will then be swiped up and used by the Cyberdark monsters to provide a stream of 2000+ Atk beatsticks with which to maul your opponent. Five-headed can be tough to obtain, but it really kicks butt and is a great game ender. The rest is mostly standard issue dumping, trap removal, and controlling cards.
