I'm not sure whether or not to put this here, so hopefully this is the right place!
Recently, I've been playing around with Kirby's UTilt, and I found something pretty cool. It's very hard to pull off, but if you do, you can potentially take a stock off of your opponent.
If you're facing the opponent and hit with the tip of UTilt, you can footstool right after it. I'm not sure who it's guaranteed on, but I know that it is on Pikachu, Falco, and Ike. Because it's such a weak hit, it sends the opponent into this half-hitstun state where they can't air dodge or perform a move right after being hit. However, it only works between 0 - 20%. After that, it's impossible because they can react right out of it.
I thought it was pretty cool. You have to buffer a FF Nair to get a guaranteed jab lock, but if done correctly and at an end of the stage you can potentially jablock someone to ~65% and get a forced get-up Grounded Hammer (Or whatever you want. I like using the Hammer).
And on a much smaller note. Players with poor DI can be footstooled after FThrow->Uair->UTilt. Now, it's not always guaranteed. Sometimes you sweetspot UTilt, but most times you put them in that same half-hitstun state and can get a footstool if they DI'd incorrectly. That means you're starting the jab lock at ~23%, which means you can end it at ~78%, which means a Grounded Hammer is almost a guaranteed KO.
So far, I've only done it to Ike and Falco.
Oh, and facing the opponent backwards and using UTilt can also lead into a footstool for certain characters. Again, I have no idea how many it works on, but it does on Falco and Ike. And it only works between 0% - 10%.
I know it's a pretty improbable situation (landing UTilt while facing an opponent or getting that UTilt at low %), but hey, anything to help Kirby, right? XD I'd love to pull this off mid-match (preferably after taking my opponent's second stock).
I'm not very good at buffering the FF Nair, but I do consistently footstool. If you guys want a video or something, I'd be happy to get one up this week for you! :D
