Notes & Combos
This is a standard Mathmech list without the firewall engine, if you want to see some combos I posted them on replays.
The most important thing in this deck(in my opinion) is knowing how to use small world, for example:
- any cyberse(except mathmech multiplication) -> dotscaper -> (max "C", ash, any cyberse(except mathmech multiplication))
If you are interested in some more targets I'll post them here, if not you can check the replays for combos:
-
droll & lock bird -> parallel exceed -> any cyberse
-
ash -> dotscaper -> (max "C", ash, any cyberse(except mathmech multiplication))
-
max "C" -> dotscaper -> (max "C", ash, any cyberse(except mathmech multiplication))
-
any cyberse -> parallel exceed -> any cyberse + droll & lock bird
P.S. Replace harpie's feather duster, I only play it because I have a royal.

I've seen people play Gamma package with Omega in Extra Deck because they would respond to a monster eff when activated right after Circular's Would you consider it?

Gamma is a good hand trap, I would not recommend it in this deck for 2 reasons, the first is that Gamma is at 2 in Master Duel, the fewer copies you have the more likely you are to draw Driver(instead of Gamma), the second and most important is that Gamma turns of Transcode Talker, this stops you from building the Firewall Dragon Singularity end board.
You can go ahead and play it, I personally prefer Droll & Lock Bird since the Master ranked is filled with Superheavy Samurai and other random decks that lose to Droll.
