The comic art would be a great source for one of these! Back in the day (~2005) I made an attempt at a Bionicle TCG. Still have a couple of hand drawn/photocopied decks and it was technically playable (unsure if it was good, however). At one point I actually tried my hand at rendering a card (vs handwritten ones), creating this out of Flash + Blender, which are not the tools for the job.

What I appreciate about yours is the desire to keep it simple. Mine had a lot of token/stat mechanics and I think relied on the card's physical position on a playing field as well. No pick-up games standing in line!

I don't have much experience with CCGs vs TCGs, but am down to try when you have it on a simulator.

First, thank you for your interest!  And for it's worth, I think your card design actually looks pretty good.

Since making this post I've decided to give the game a generic fantasy theme.  Unoriginal I know and using characters from established franchises like Bionicle, Star Wars, LOTR and whatnot had its appeal, but I feel like plain fantasy can reach a wider audience.  Especially, since my next largest source of interest for this game is a discord I'm in for a SW board game; if I themed this game around just Bionicle, they'd probably be like, "What the heck is that?" 

A lot of other things have been eating up my time lately so I can't say when I'll have the game available to play, but I did make a post on my board gaming blog with the rules and some other design notes if you'd like to read them.
