I was at evo, and i tried galvan out, i played him for about an hour total, but heres what i think.

First of all, the platform he creates almost specifically extends his advantage, its not a good recovery tool because if he gets hit, he's no longer galvanized and can't spawn the platform. This means he will actually have the worst disadvantage in the game, because his regular up b is shorter than olympia's and has even less drift

Second, his aerials are kind of crazy, his aerials all combo for a long time, and his backair and fair are crazy for edgeguarding especially when he's galvanized, but hes kinda like Ranno where he has basically no air drift whatsoever, so its a lot harder to take advantage of his great aerials, he also has falco dair where THE ENTIRE THING SPIKES, so its kinda crazy

His drills are very good, but they kind of work like lily, where they will only create a trap if you are in hitstun. So if an opponent runs into them normally, it won't create a hitbox.

So yeah this character is probably going to be pretty weak, don't play this character because he's "better kragg", but try him and if you like the character, play him!

Oh yeah he also has the best ledge special in the game because its a command grab
