Effect: Help you smash your way through the tournaments!
When:
During gameplay.
How:
If you are playing against a "slow" or "tricky" player this should help, when they return the ball try not to let the ball bounce that way you will keep you on your feet. Also if you see a star get underneath it and press "A" and "B" simultaniously to smash the ball straight past your opponent you know this would have happened as a purple/pink line will follow the ball for a second.
