Ladies and Gentleman! Open the curtains of the show. Behold, I present you the "Orcust Codebreaker" Deck, using the most newest cards from Eternity Code Booster Box!
The main idea is to send "Codebreaker Zero Day" to the Graveyard, or bring it to hand by different ways, using the Orcusts and Goukis to fullfill the field and Summon "Codebreaker Virus Swordsman" and "Codebreaker Virus Berserker" to the field. This will cause the opponent's monsters that are linked to "Zero Day" to lose 1000 ATK each if they are not "Codebreaker" monsters, and I can destroy up to 3 opponent's Spell / Traps with the effect of the "Virus Berserker".
This is a going-second focused Deck, but it can also do very well by going first. If your opponent doesn't use Links, you can only use Codebreaker as a way to fill the field, and to add cards from the Deck to the hand via "Codebreaker Day Zero", while using your monsters to Summon the Orcusts.
You are free to download the Deck and try!
Have fun!
