"Gravekeeper Artifact" Deck 2016

Playing

In order to aim for his royal tribute from the first turn, I throw in a lot of draw cards to make it easier to call in.
Use various searches and draws to collect Necrovalley and Royal Tribute in your hand.
Always lay down any Artifacts or Spell Traps before activating a Royal Tribute! The compatibility with Artifact is outstanding.
Note that you can't move anything unless you have at least one of Movement or Atheism when laying down 5 cards.
Deploy his Artifact on the opponent's turn, and attack with Xyz such as the Pleiades on the return turn.

Strength

Basically, it's good to always have Necrovalley on it, so it's good to have Necrovalley, Commander, or Terraforming in your hand so that you don't mind being broken.
《Card of Demise》cannot deal damage in battle, but it can be used in main 2 after battle, so use it according to the situation.
Consistency, 《Cards from the Sky》, and 《Card of Demise》have almost the same disadvantages, so use them sparingly.

Weakness

Decks with more than 2500 large decks (Blue-Eyed, Black Magician, etc.) and Decks with less GY usage
Of course, chain burn etc.
It's painful because Tribute doesn't work very well for Decks with extremely few monsters.

Customize

Necrovalley not only can simply crush GY resurrection cards (《Monster Reborn》and libide) and fished Effect Monsters, but it also blocks removal, so it interferes with the effects (Monarch Spell, breakthrough, etc.) that are used to remove many GY cards recently. It has a wide range and is highly disliked.
I think Deck is quite complete.
