Wizard: I'd completely remove the Gate of the week shit, and focus on all the stuff that matters.

I'd have White Wizard be the same badass, but I'd let his scheming happen on screen, so his tragedy has time to play out and not just come from nowhere with some rushed explanation that explains nothing and makes no sense.

I'd have Gremlin in from the start of the show, and I'd both give him and Medusa actual powers, and stuff to do. As both of them were basically non existent and often out classed by of the week Phantom's that had much cooler designs and actual unique powers.

I'd make Beast/Nitou be the hero he's been for the last few months, from the start. I don't know why he started as some comic relief mayo obsessed weirdo, but that character was shit and I'm grateful it was dropped and they acted like he never existed. I wish he hadn't.

I'd have each Style/Dragon be its own Rider and then Haruto combines their powers together to make Infinity, rather than that CGI abomination that is All Dragon. And rather than having four stock Mages at the end.

I'd have Koyomi be an actual character, or give someone else her arc who was actually in the show.

I'd give the whole Tokyo Ritual thing longer than five minutes in a single episode.
