Corrin's dragon transformations are pretty metal so it's a shame how everyone writes them off because of "sword bad".
It's funny because Kirin are the absolute opposite of metal. lol
Honestly, Corrin's dragon stuff leaves me pretty underwhelmed. When I play a dragon, I kind of expect more empowering dragon magic n' stuff and less "my finger is a stake". Don't get me wrong, it's an interesting take on the ability, but I'm just not really here for it. It doesn't really help that Corrin kinda feels like Lucina with a projectile and a mobility skill. It makes him play differently sure, but he still very much feels like he fits the Marth mold in a way that even Roy and Chrom don't.
I do like that Corrin is based on a Kirin though. It's a pretty unique inspiration, and it fits his "I don't like fighting" shtick really well.
Although I find Byleth "fun" to use, I'm disappointed with the direction the devs went with the character in using the Hero's Relics rather than Byleth's own abilities (Sword of the Creator, hand-to-hand, Divine Pulse, white magic, battalions, etc.).
It's funny, because "add more weapons because sword bad" actually made him less unique than his other stuff would have.
The cape became the Down B, and that FLUDD had been replaced with a Cappy throw, which could also be used as a jumping platform. Not just to reference Odyssey, but to make Jumpman have a more unique platforming aspect.
This is kind of what I was thinking, but with a few extra changes.
I'd have given Link the Glider as an Up B, absolutely taken away the Boomerang that is barely in BotW, and either given him more references to the Champions and/or the the Sheikah tablet. Most likely more of the tablet, to reference the Cryo and Stasis (I'd also replace the Arrow, though that's less necessary). With Magnesis as a grab.
Champions could be primarily cosmetic- using the Daruk's shield as his shield, Mipha appearing for Link's respawn, Urbosa's Fury as a Smash attack (could replace a sword Smash- there are too many), and I suppose Revali would be for that Up Special.
I'd leave Bow and Arrows. The bow is very important to The Champion of Hyrule moreso than pretty much any other Link. Not really sure about Magnesis as the grab since it doesn't really work that way even against robot enemies, but Stasis would be the single best thing they could add I think. The ability to freeze bombs, arrows, and opponents alike and change their trajectory and stuff would be quite the thing.
As for the Champions, I'd have Rivali's Gale factor into his Glider Up Special like most would suggest, Urbosa's Fury create a paralyzing electric field if you charged a Smash Attack for a bit, Daruk's Protection give Link a Yoshi style shield that can't be shield poked, and Mila's Grace be an entirely cosmetic "effect" that procs whenever Link comes back from being K.O.'ed.
I am sorry but I am not buying the cape as the down b. It seems too odd, and given its use in the air....no.
I thought that too, which is why I turned it into a hammer swing that does pretty much the same thing. Mario's hammer is a bit more timeless than the Cape Feather anyway.
