Make sure to accumulate enough coins though. When rankings come up, get only attack boosters and health boosters. After 2 or three rank ups, learn at least 1 new move. Moves that will help you deal with multiple enemies is a great move. Get moves with multiples like hurricane kick, hook kick, jump kick, and low spin kick which greatly helps you. Multiples forward and backward fist spins you can get later. When you have ranked up higher like purple or dragon, moves like grabbing and countering you should get first. Always get all of the health and attack boosters possible in the current rank before moving in the next rank.
