Notes & Combos
After a lot of theorycrafting and testing, this is (probably) the best way to play cyberdark. I went on an eight game winning streak from D2 to M5, so it definitely works, I think.
The SHS engine adds a lot of consistency and gas to the deck, and the Armored Xyz cards increase the ceiling of the endboards by quite a lot as well. The main idea is that you'll use Wakaushi and Booster to get two level fours on field to make Gigant, which can then search Core if you don't have it. You can then use Gigant to go into Fortress, which gets you an extra 2 negates plus an attach if you have Cyberdarkness on the field. Your ideal endboard is Cyberdarkness equipped with Cyber End, Fortress, and sieger equipped with Gigant, with a set Full-Armored for a total of four interruption.
I was originally playing Clockwork Night plus Regulus too, but found it to be too bricky. Same goes for Infinity, you don't want to sacrifice consistency for potentially one extra negate. Feel free to cut Lightning Storm and TTTactics for more Veilers, the only reason I didn't is because I only have the one. Do not run Imperm instead, the anti-synergy with SHS isn't worth it.
If you have any questions, feel free to ask.
