I'm still trying to figure out the right balance of defense and offense. I should probably look up Slay the Spire strategies or builds, but my brain is convinced it would be cheating for me to do that, so I'm just muddling through myself.

Definitely! I've made a few for the character I really wanted icons of, just messing around so far. I think it reminds me of gif-making in that respect, which I got into a few months ago. Initially it was just for making pretty edits of my MMO characters, but then I realised I could make a gif of One Scene I'd searched through a show's entire edit tag up to the episode air date to try and find, without any luck.
