Here's a video of some nice WFT play by Daiki that I would argue is near AnTi's level. He uses him at the 10:00 mark:
Daiki didn't respect Falcon enough and wasn't aware of his character's weight, dying to a people's elbow from near the middle of Town & City. He seemed to know what he was doing and gave the Falcon (Shadow) a run for his money. I know I'm digressing a bit but I think WFT vs. rushdown characters like Fox and Falcon is a good MU for WFT, since s/he's capable of hitting just as hard and being just as fast, and said rushdown characters are more vulnerable to any of WFT's comboing moves. Plus WFT has good projectiles, and vs. Fox specifically, the reward from conditioning and punishing reflector is huge. Meteoring their recoveries isn't too difficult either.
Here's Megafox as WFT @7:15 (vs. Espy's Meta Knight) and 11:15 (vs. Espy's Pac-Man):
These weren't serious picks unfortunately, but competent nonetheless.
Now here is someone who actually mains WFT, goes by the tag "FunCrazyFish" and I remember at the first San Antonio monthly he took Denti to game 3 (no video tho :<). Here's him fighting Paw (ZSS):
I like how he used the header soccer ball as a sort of "sponge" in game too, although it didn't connect with anything, you could see that it was placed that way to absorb attacks. I also really liked the baiting with Deep Breathing and the off-stage aggression.
vs. Sylveon (Donkey Kong game 1, Ganondorf game 2):
Another good match, though there was intense respect for DK's KO power. It was reasonable, too; heavies can be scary as f***, especially Bowser. O_o In game 2 FCF got tagged by a few devastating moves from Ganon, in the end superior mobility and off-stage game came through.
vs. Espy (Sonic)
A pseudo-heartbreaker because FCF would probably have won game 2 if he hadn't made that mistake on his second stock.
Highlights the Sanic MU.
There is a video of FCF vs. KPrime (a notable Pikachu main), but in that video, FCF uses Palutena games 1 and 2, and I can understand why: Pikachu dodges all of WFT's moves 95% of the time, especially grab and f-tilt. That MU is so frustrating and I think it needs to be addressed in a patch (simply increase the width of the grabbox on grab and the hitbox on... all of WFT's normals lol, at least to where they can actually connect on a grounded Pikachu).
