6B to 6C is a super easy starter that starts with an overhead then attacks low.
This way if they are blocking high the second input will hit and launch them and if they are crouching and blocking the first input hits then both will land and launch them.
Once they are airborne dash(66) and 6A to launch them again before they land and cancel into a jump to start comboing in the air. Easiest is B - C - JC - C - Belial Edge
