8/10

You seem to know that discard costs don't trigger the effects of the dark world monsters. Only discard effects does. Which is why I don't see such cards as Dark Core or Tribute to the Doomed. But in a deck full of fiends, why don't you add a Dark Necrofear for bonus?

also(this is just me) i think a dandylion wouldnt hurt cause of its effect and brron's

take out zure and put another brron and add 2 extra bottomless trap hole instaed nobleman of crossout and pot of avarice. add a torrential tribute instaed a beiige, another DW dealings instaed the other beiige and another DW lightning instaed a kahkki. sangan and a rigraas leever could help u. so add them in side... and this is all

You did good, however in my experience in making Dark World decks I found that Scar is kind of worthless ... that's my opinion though. Mask of Tribute is an awesome card for Dark World decks because most of the monsters are special summoned and barely any of the mosters are tributed (if not none).

On the subject of Feild Spell cards, Necro Valley can be an awesome tech with Royal Tribute considering that Royal Tribute acts as an extra Card Destruction. Card of Safe Return works when you can special summon one of your many monsters form the grave, netting you an extra card in your hand also!

If you wish to make a side deck you can add Deck Destruction Virus for when you don't have a Mask of Tribute activated (the case being you can summon Goldd or Sillva fast enough).

I run 3 Dark World Lightnings for the extra bonus of feild advantage that it gives you from flip/ face down mosters and spells and traps, also you basically use it to summon one of your signature Dark World monsters.

;;>_> As you can see I have a lot of experience in Dark World and if ever need help or wanna test it just PM me, after all I haven't really used Dark World in a while (despite my ambitions to do so lately) and would love to knock it back into my deck holder =P. Who knows maybe we both can learn more things in the ways of Dark World

i personally think that the deck isn't well balance with the right amount of less then 5 level monsters and there being more spells and traps i think you should add 1 more of the that are x2 and add some other dark monsters with high attack nd have a gaint germ annd i think u should have 3 zure knights

add COSR

put cards that help on reducing damaga and destroying monsters as hallowed life barrierand lighting vortex

maybe an dark deal?

just add other dark deal cus then u an use the effects of the dw monsters

Hum.. Dakness, I really cant help u out on decks lol, because I'll be giving you my top decks secrets. Those decks that I can help out are found from the site.

But then I have 4 series of Dark World, just like I have 4 series of Gravekeep's and 4 series of D.D. decks.

The first serie of those decks relies on basically their own cards support so here's the recipe of DW 1.0

Belige, VoDW 2x
Broww, HoDW 3x
Brron, MKoDW 2x
Goldd, W-LoDW 3x
Kahkki, GoDW 2x
Morphing Jar
Reingn-Beaux, OoDW 2x
Silva, WoDW 3x

Book of Moon
Card Destruction
Card of Safe Return 2x
Dark World Dealings 3x
Dark World Lightning 3x
Dragged Down itG 2x
Gateway tDW 2x
Monster Reborn
The Cheerful Coffin 2x

Dark Deal 3x
The Forces oD 2x

Dark World 2.0 relies mostly on semi-fiends with 4 darkworlds and 2 of its card supports. Also included some of the Top 25 cards (see the site to view the list) http://konamiworldchampionship.webs.com/apps/blog/show/222569-countdown-cards-from-yu-gi-oh-world-championship-2008-

Dark World 3.0 relies mostly on Sky Scourge Norleras (I also have a Kuriboh deck which relies on Sky Scourge Enrise) with 4 darkworlds and 2 of its card supports. Also included some of the Top 25 cards (see the site to view the list)

Dak World 4.0 relies mostly with Hand destruction such as Deck Devastation Virus and Crush Card stuffs with 4 darkworlds and 2 of its card supports. Also included some of the Top 25 cards (see the site to view the list). Also this deck is found from one of the ghost duelist from WC 07.

But then again these decks are my tops lol, and sometimes switch on which one to use.
