Hint: Sabrewulf: Ultra combo:
Get your opponent to very low energy, until the life gauge is blinks. Use the Sabre Pounce -- press Right, Left, A, Right, Left, B, hold Left and press A, charge Right, then press Left, A. After the opponent flies high in the air, do the Sabre Pounce slightly before the opponent falls. Note: This takes timing.
