Edit: STOP TRYING TO MAKE THIS A DARK WORLD DECK.
... IT'S A NECRO RETURN DECK... Not returning the favor on dumb fixes.
(Will return favor on smart ones)

Ah, I need to fix the spells and traps, didnt work right

I could see Pot of Avarice in here. Personally, I would drop one Necrofear and one Dark World Lightning. Add in a Dark Ruler Ha Des and another Goldd, and two Browws for draw power. Card Destruction could also be useful in here.

It's been my experience that 3 necrofears dosen't work. Try dropping one for a sangan. Also, try to work in a Hades.

Nice deck though.

Please return the favor on my Harpie deck.

Well, here is my suggestion.

- Magical Merchant
- Magical Merchant

It is good, though I really don't like this card in this deck.

- Spirit Reaper

It very random in my opinion.

- Night Assailant

You really don't need this card in your deck.

- Nobleman of Crossout

This is gonna be an aggressive format. So this is a good side deck choice, though main deck is not good.

- Premature Burial
- Call of the Haunted

Well you can use other recursion.

- Enemy Controller

Never really fond of this card in this deck.

+ Gateway to the Dark World
+ Gateway to the Dark World

Really this card is good, and not attached.

+ Morphing Jar

Morphing Jar is awesome for this deck.

+ Broww, the Huntsman of Dark World
+ Broww, the Huntsman of Dark World
+ Broww, the Huntsman of Dark World

Broww, Provides Drawing Power.

+ Goldd, Wu-Lord of Dark World

Goldd, is awesome in this deck.

+ Creature Swap
+ Creature Swap

Swap is one of key cards for this deck.

Nice Deck 9/10

Check my deck in my sig.

Ok maybe I need to explain the deck because everyones trying to turn it into a Dark World deck... the point is to DUMP fiends into the grave yard (NO POT OF AVARICE) and then use Dark Necrofears effect to remove three fiends from play, eventually ill get some decent fiends removed from play and play Return from the Different Dimension...

This is NOT a Dark World Deck... Fiend.

-1 Giant Trunade
+1 Soul Release
- Sillva
+ Jinzo(Just to be cute, let them remove it, he'll come back)

If you want a RFP Fiend Deck, Darkworld is hard to run with, Maybe throw in a Magical mallot or Reload, Card Destruction may hurt you more than help you depending on what youre going for. Try a Torriential Tribute while summoning your own for adverse effects. Try out combos and see how it goes. Last Will and (Sacred Pheonix if you find a Lightning Vortex happy opponent). Sorry for the first fix, it just looked like a DW Deck with Necro Support. Try a second Goldd if you dont like Jinzo, Sillva's effect may hurt you if youre going against someone running 3 Goldds, or a DW Deck.

The reason for Soul Release, is that you have Two RFTDD, Say you run into One, and no sign of Necro. But Also... Next to be Lost could find its way in this deck, if you want to Dump, throw two of those in there, smack your Giant Orc, or Goblin Elite(another idea) and throw them in the grave. Either way, Its a good deck just the way it is. Just be weary of Necrovalley, Macro Cosmos and Anubis!
