Seeing as you got to 1300+ i don't think it needs to be changed in any way because it suites your playing style.
This deck has brought me multiple times to 1300, BUT Sigma will be banned in a week. What do I do then? Like I said, I was considering Cyb Lhia, but I'm not sure if her poison of 2 will be enough to win with a low hand... Should I then give it a try or think of a completely new strategy?? And if I decide for Vortex, should I still use Hattori/Neloe or go with Dregn/Yumi? I'd miss damage reduction, but it would add some safety and more ko opportunities... What should I do?
