"Gravekeeper Shaddoll" Deck 2018

Playing

Take the lead first.
If you can get ahead, aim to set up a shrine or set up a midrash for the first move.
If you have 《Royal Tribute》in your opening hand, activating it has a higher priority as it can trigger the opponent's hand to drop.
Don't keep shrines and midrashes, just think of them as a way to slow down your opponent's tempo.
While your opponent can't move, use various Shaddolls, psychics, summoners, and priests to gain advantage and keep your hand running.

Strength

With Necrovalley applied, a psychic and his Shaddoll can cast Midrash. But if you can put up a shrine, that one is stronger.
With 《Dark Renewal》, he can send Shaddolls and Summoners to his GY, while getting the next Summoners and Priests out of the Deck gives him an advantage.
Also, it's good to gain an advantage with his Shaddoll while handicapping your opponent with 《Royal Tribute》.

Weakness

First of all, there is not enough removal.
It is quite painful if a big one is put out or a system creature is put out first.
There are a lot of searches, so if you can't draw Necrovalley in the first hand, please give up when you're the opponent Sandra. If you draw Necrovalley, you can negate the fusion resistance. From there, do your best to handle it with combat or dimensional magic.
If you know that your opponent is Sandra, you can switch to high beat by switching to skidre and sin from the side.

Customize

This time, I'm focusing on the synergy between Gravekeeper and Shaddoll, so there are less general-purpose items like 《Infinite Impermanence》. So I think you can make it more versatile if you like.
Since you can't play 《Called by the Grave》under Necrovalley, I think it would be better to remove 《Royal Tribute》and add a hand trigger.
