DandyPenguin beat M2K, not Raito.
Also Fox is still a bad MU. Most Fox players are conditioned through other MUs to play aggro and thats what makes the MU look even for DH bc DH punishes rush ins and, even tho we didnt see it, can break out of Utilt/Uair/Fair with Can (Fair and Uair has to be predicted)
If Fox uses lasers to flip can and carefully applies pressure with his speed, he wins. Most Fox players either just play their game (Larry) or focus too much on the projectiles (too many lasers, Shine). We saw Raito stand behind Can when Larry was laser camping. All you need is to flip it once and apply pressure cuz the Can is now in an awkward state. It stuns Can for a bit.
Duck Hunt's hardest match ups, in order:
Bayonetta, Cloud, Sheik = ROB, Link, and Shulk. Other semi toughies are Fox, Rosalina, and Pikachu, but theyre managable. (DH has other losing MUs but those are the most notable ones)
Also yes, DHs neutral is among one of the best in the game. It's the best of all the mid/low tiers imo and its on par with the high tier threats. Its the greatest quality of the character, along with being able to frame trap and cover in his defensive options (Can + Shield, break out of combos frame 1, intercept hoo haas with stray can, best spotdodge, good air dodge and roll)
