Ok deck. Im going to suggest some changes but you might not be able to afford them all so just change the ones you can:
C Beast ---> Dregn.
Lehrg ---> Dagg.
You could also change C Blade to Cyb Lhia and Onyx to Lovhak.
Also is 6 consecutive wins good for first time?
Or is it bad coz i think its bad
Its good for your first try.
