Maybe 1-2 Dark Grephers.Also If you add the grephers then a RotA could help you a bit.
You run a lot of darks in grave so a dark creator could be a good choice.
Add the limiter removal.It will help you OTK your opponent.
-2 Dark Eruptions You run cards that need grave to be effective (FF,Cyberdark Impact,DaD,If u add Dark Creator,Overload Fusion,CoTH,Dragon's Mirror) so Dark Eruptions wouldn't be that a good.
-1 Smashing Ground better in side deck
Test it and tell me how is it!
