Dream Cancel forum member and Mai wiki page editor Great_Dark_Hero has created and uploaded a video showing a very cool combo and blockstring that ends in a very tricky overhead mix-up.
“Mai can cancel her cr.A, cr.C, and whiff cancel her cr.D into her ground Musasabi (d charge u+P) If Mai does cr.C, d charge u+P, into Ukihane (air d.B) it will combo naturally and it is true block string that is relatively safe. When this is comboed into Ukihane, it will register as a overhead, thus creating a true overhead mix up combo. “
