Thank you stealth. Prime, it isn't INCREDIBLY EASY, but it is still inescapable unless the pikachu ****s up. It can get you to the edge of the stage, and then you can just ****ing F-smash them...it's not like it HAS to lead to death, but its EASILY 40-50% if you get it, especially if it isn't one of the lighter characters who can DI a lot...
Also, for people saying it isn't applicable, there are SEVERAL ways for you to set it up very easily:
FF-fair->uair if you land behind. Uair and u-tilt both come out in 7 frames.
Oh hey, the opponent hits the back of your shield after you QA away from them. OOS uair.
D-throw-uair(most likely full-hopped)
Lol i wouldn't even need this to beat you
