Experimenting with Greninja on 3DS, when I discovered that while standing on the ground and performing the up-b, then angling it like a backwards wavedash can make him slide. Depending on the angle the farther you slide. You'll know if you did it right if you see a single water pellet fly at the angle of where the control stick is at.
Pros:
-Useful for Spacing
-Pushing jumping opponents away
-The water pellet can gimp recoveries, but only if the opponent recovers too high
Cons:
-Still have the same landing lag from the regular up-b
-It is easy to accidentally do Shadow Sneak
-If expected, the opponent can punish you.

Currently I am still experimenting on a way to make this useful for other situations. Feel free to put down your opinion on this.
