The initial 12% can be obtained by doing a whiffed grab charged fsmash desync into Popo regrab.

From here, do the Murasat combo. The first delayed fh fair is true if done right but is admittedly somewhat frame tight. I messed it up in the video but as Robin doesn't have a frame 1-2 escape option it was likely true anyway.

From here, you want to fast fall with Popo, land, and grab. This is the part I had trouble with. As I can see the blue circle, I think Robin can actually tech the fair spike here, and that I'm grabbing him on his way up after the bounce, but I also feel like I am not fast falling with Popo fast enough, so it might be possible to get a true grab. DI is also a concern. Since I am looking for a **reliable** way to 0-to-death here, these definitely decrease the viability of this combo.

If it's not possible similar to as shown, then the alternative would be to lower the % so the fh fair does not send into tumble, and then find some way to deal an extra 3-4% before the fthrow fair so that it can secure the stock even vs. characters like Robin with recoveries that can make it back from very low.

While it is possible to try and footstool the character after, I do not find this to be a reliable option, since you kind of have to go down and guess where they will be to footstool them, and it can be easy to fail, at which point you have given up your advantage state.

Also, the final fthrow fair has a full hop from Nana into a delayed fair to once again avoid the shorthop multiplier of 0.85x, which is what allows this to take the stock—normally you would do shorthop fairs but since these do less damage/knockback they will not give the same result. In fact, using timed fullhop fairs is the only real difference between this and a common murasat follow-up, so in that sense it is nothing special.
