Notes & Combos

Used this deck mainly to climb to M1. The deck can break through quite a few boards and has plenty of gas (granted that the opponent has 2+ cards in hand for K9 NS).

End Board looks like: St. Azamina, Silvia, Ripper, S:P, Chaos Angel... with Release and Gaze set... and Izuna in Hand. Very difficult board to break with 2 omni-negates.

Deck does die to Fuwa, Maxx, Purulia, Droll, but what you gonna do? ¯\(ツ)/¯

I did experiment around with adding Fiendsmith and cutting a bunch of Azamina cards for more resilience vs Droll and Purulia, which was also good, but I like piloting Azamina since that's what I'm familiar with.
