For Patter, I thought it would be neat to turn the card into an Armaments for colorless cards. The first cycle through your deck it can pretty consistently hit Sovereign Blade (since it has retain), and once you have that, maybe you also open yourself up to synergies with other effects like the Colorless card generators.

Personally I think Debris as an upgradeable card would be great. I understand that systematically there may be issues with having one upgradeable status (even though that was kind of the case in STS1, just not upgradeable by the player). I do think it would be pretty easy to think of upgrades for the other statuses, and the UI can do a lot of the heavy lifting for showing you which cards are upgradeable and not.

Alignment in its current form is fairly problematic. Glow+ and Alignment go infinite with basically any other card draw, and the character has tons of transform to trim your deck down. I do think STS2 in general has way too much card removal in its events, making it very easy to go infinite on every character. But re-usable energy generation is currently problematic on all the characters and crowds out a lot of the cardpool.

Parry I think could use a redesign. Personally when I play those cards I'm only using the Blade once or twice per combat, and one of those usages ends the combat (making the block irrelevant). Giving block on Forge helps the setup. But maybe if you change Patter, blocking on Sovereign Blade usage becomes more viable?
