Brilliant idea there.
Really looks interesting.
Chelsea:if he adds shoppa,then everything gets screwed up,'cuz there has to be 7 schemes.
It should be like: A deletes 1 scheme,then B another,then again A's turn until one remains.
and well,about who is starting,the higher overall ranked sounds reasonable.
P.S: you typed : groups bo1
ko's bo3
and again groups instead of finals
