I think we can all agree that the reason why we play Buster characters is the feeling we get when we get a successful throw. That escalation of excitement and realization that our throw catched, the rising feeling of our heart in our chest as our character carries the enemy high into the air, and finally the feeling of overpowering victory as we send the opponent crashing into the ground dealing over half their HP or a KO. Also, watching your friend's reaction when he gets caught by it (esp. Pot's HPB) when you're on the verge of death and turning the game around to your victory.
Oh that sweet sweet feeling.
