Smash Champion
While fooling around with Wii Fit Trainer the other day, I did a lot of ledge camping with Side B. Then I was messing around with doing it in Endless Smash, and the result is that you can go the ledge, drop down, double jump and then Side B and the ball will KO anyone it hits. Then you can just grab the edge again because of WFT's slight rise when she performs Side B. Note this is neutral Side B. If you're so inclined, you can also be off the stage enough to charge Sun Salutation. I usually do this by ledge jumping, then double jumping and charging it, then air dodging out of the charge and UpBing to the ledge. Although it's risky. You can do the same with Deep Breathing to recover some health. But anyways, I got around 600 KOs like this. You can even use Side B to hit a Smart Bomb!!!
