Another awesome Mai corner combo... 3 meter HD combo from counter hit s.C+D...
counter hit s.C+D (has to be spaced away), qcf+A (hit confirm)
tk qcb+ABC, *wait* qcb+C (has to hit very low), DC, qcf+A, qcb+C, qcb+C, DC, qcf+A, qcb+C, qcb+C, DC, qcf+A, qcb+C, qcb+C, DC, NEOMAX = 784 dmg
Same combo can be done if you land counter hit j.C+D near the corner but timing is very situational based on height and distance...
