use Danger! monsters to get a ton of dark monsters onto the field to be tributed with Shadwowpristess of Ohm for an ftk.
Ohm is a stronger Cannon Soldier in this deck and is probably the most underrated card in the game.
This ftk is disturbingly consistent and almost 100% without removal. From my experience, it has about an 85% rate to ftk when your opponent opens with a handtrap that negates monster effects but it is easy to bait out if you go into xyz monsters with the Dangers!.
I also added only 1 Dark Room of Nightmare in the main and 2 in the side deck because you can get to it very easily but not always but is also kind of a win more card and doesn't always matter
Give this deck a fair chance and you will get a lot of wins.
