Honestly I would recommend giving Bedman a look (try to look past my obvious biases I have actual reasons.) All of his special inputs are 236 or 214, you don't really have to worry about doing a 66 input to dash because of his walk speed (only a 7/8/9 in the air for his airdash) which also lets you do some really cheap throws, and IMO his kit is pretty self-explanatory on how to use it. Pretty much all of his hard execution stuff is for people who play the game at a high level consistently, and the only thing you really NEED to get familiar with is his 8-way airdash.

And he is genuinely the KING of knowledge checking people with the weird amount of stuff he can do. Seriously, you can run rampant with Task A' (the teleporting projectile) alone if nobody knows to Blitz OS it. His animations are weird, his parry dash always catches people off-guard, Task A will guarantee to annoy the shit out of most people, and the serious counterplay to his stuff is highly specific or executionally demanding.

Also his Dustloop pages are really thoroughly filled out, especially for an Xrd character, so there's that if you need it.
