So I found something quite useful as a CP for WFT. I know not everybody allows this stage because the second transformation is a walkoff, but Castle Seige has a useful throw combo for her. Normally, when you FThrow at low percents against characters you can't followup with Fair because they fall to the ground too quickly, but using the slopes on the first (center stage) and second (the drape things on either side of the stage) you can actually get a Fair followup on most characters between 0-30%. Against the heavies, too, it's incredibly useful, as it can be used to kill if you get them in the 60-70% range-- they're just so big that the target is easy to hit. I haven't checked this on other stages, but I suspect it's also possible on some Delfino/Skyloft/Wuhu transformations as well, and potentially Lylat Cruise during it's tilt. I checked on the third transformation and it's only possible right around 25% on big characters, so it doesn't seem as useful.
Note that it's easier to accomplish in the 20%-30% range, because most characters aren't put into tumble from her FThrow until then. At 0% it's not a true combo, but it is at 20%.
It's also good to know that at 0% they are forced to land on the platform in the first transformation in a fallen state. Unless they jump out they will get hit by the fair every time (Airdodging will have too much landing lag and they won't be able to shield the Fair in time.)
This seems particularly useful as it takes advantage of how weird the hitbox on her Fair is. Very few characters can react with an aerial in the area she's approaching quick enough to stuff her Fair, and even then she'd probably win the priority fight over sex kicks like Link and Puff. Feel free to give it a try and maybe improve the concept (or help me realize why it's wrong.) Of course, this was all tested in Training mode, so if people wanted to maybe test DI on the FThrow or maybe try different %'s on different characters that'd be great.
EDIT: -Works on the outer edge of Lylat while it tilts only.
-Works on the outside of the plane on Wuhu really well.
-KJ64 works okay, slope is a bit short for it to be effective.
-Some Delfino platforms work. Stairs on Delfino work.
Seems to work better on specific characters (i.e. doesn't hit Diddy well but hits Mario 100% of the time.) Likely weight based.
