Necrovalley Shutdown

Since Gravekeepers are going to be getting more popular as Absolute Powerforce approaches I've decided to look at some interesting Gravekeeper builds. The one that caught my attention was the Necrovalley Shutdown. It possesses raw power that could take down any top tier deck with ease. I took it upon myself to build my own version of the deck and test it out. So far its been able to beat French Twilight, Blackwings, and D-Hero Zombies. I haven't had the chance to test it against Glad decks yet but one of my friends pointed out that I could side into a Skill Drain version of the deck. I'll have to try that out soon. Well heres the deck.

Monsters:18
3 Gravekeeper's Assailant
3 Gravekeeper's Commandant
3 Goldd, Wu-Lord of Dark World
3 Sillva, Warlord of Dark World
2 Brron, Mad king of Dark World
3 Broww, Huntsman of Dark World
1 Morphing Jar

Spells:16
3 Necrovalley
2 Royal Tribute
3 Dark World Dealings
2 Dark World Lightning
2 Allure of Darkness
1 Card Destruction
1 Heavy Storm
1 Mystical Space Typhoon
1 Brain Control

Traps:07
3 Rite of Spirit
2 Bottomless Traphole
1 Mirror Force
1 Torrential Tribute

The point of the deck is to get Necrovalley on the field as quickly as possible. It will shutdown all graveyard removal and graveyard targeting effects. All the top decks get hurt by this. Once Necrovalley is on the field you need to be able to Royal Tribute. Royal Tribute requires Necrovalley on the field to activate. It forces both opponents to reveal their hands to one another and to discard all monsters to the graveyard. With the Dark World monsters being able to work under Necrovalley it screams Dark World abuse. Rid your opponent of their monsters while you draw or special summon your own. The Gravekeepers chosen here work perfectly with Necrovalley. The Commandant searches Necrovalley and while both are on the field it becomes a 2100 hitter. The Assailant becomes a 2000 beater when Necrovalleys on the field and allows you to switch you opponents monsters battle positions when you declare an attack. You think the opponent has Honest? No problem. Have your Assailant attack their light monster and switch it to defense to avoid Honest. The deck doesnt run any tuners so the possibilty of an extra deck is pointless unless your able to Brain Control a tuner. Or you could remove a copy of Rite of Spirit for Plaguespreader Zombie to have some kind of Synchro action. The deck is really cheap to make since most of the cards are common and rare. The holos shouldn' be too expensive either except for Mirror Force and Allure of Darkness. In my opinion this deck is really good. Its unexpected and its a force to be reckoned with. My only concern is a Tragoedia or Gorz. The deck doesnt have many outs to them so if your trying to build this deck you might want to make some modifications like adding Fissures or Lightning Vortex. The side is totally up to you guys but I do recommend a full set of Skill Drains for Glads.
