"Slightly Rank-Up-Magic specialized Umbral" Deck 2013

Playing

All members have DARK, Fiend, and DEF 0, and the theme "Umbral" specializes in self-destruction attacks with ATK 0 and rank 4 Xyz. It is a Deck that mixes 《Kagetokage》, which is easy to use as Xyz material and can be searched with 《King of the Feral Imps》, and 《Reptilianne Vaskii》, which can be Special Summoned by releasing ATK 0.
Depending on whether or not Rank-Up-Magic is in your hand, the operation method will change, so I will write it down.
・ If you have Rank-Up-Magic in your hand
If you can only get level 4 x 2, fight with the rank 4 xyz you got, or CXC to Hope Ray V or Giant Hundred depending on the situation.
Aiming for a combo with Master Key Beetle, we have also introduced Darkness Decks and enshrinement, so if they are coming, Key Beetle will also be an option.
This Deck's trump card 《CNo. 104. I would like to Xyz Summon Masked Demon Umbral, but depending on the situation, it might be better to use Ruler or Ouroboros.
"Spirit Barrier" is introduced to reduce the risk of taking a large amount of damage from a suicide attack.
Since Shin Key Law has been introduced to the extent of trial, it may be possible to remove it
・ If you don't have Rank-Up-Magic in your hand
Depending on the situation, use Mae Stroke, Hope, Korn, or 《King of the Feral Imps》to fight.
If you can get level 4x3, there are also rulers and ouroboros

Strength

C No. that can be issued with Rank-Up-Magic. both have strong effects.
Suicide bombing is essential, but if you use Unform and Ghoul, you can also perform a 4x3 Xyz from two cards in your hand.
Another strength is that it is easy to shoot 《Eradicator Epidemic Virus》from the presence of Key Beetle.

Weakness

If there is no way to issue Rank 4 Xyz with 《Stygian Dirge》etc., it will be very difficult.
Also, since most of his Umbrals have his ATK 0, it is very dangerous even if they are prevented from deploying.

Customize

I just assembled it and it's still a mess, so I think there's room for improvement.
Increase the number of Key Beetles to specialize in Key Beetles, remove Rank-Up-Magic to make it a normal Rank 4 Beat, or insert Tannhauser Gate to aim for a Rank 5 Xyz Summon...
