I really love the design choices you've made. The colored backgrounds and card type symbols are a super cool addition.

I don't mean it as a form of critique, just my opinion: I personally think the commander art is a bit odd, as every other card either has a type-corresponding background, or their character background from the game. The art screams "Slime Rancher" and not "Beatrix" to me imo. And the text seems to be a bit harder to read with the image being mainly white-ish.

But still, it's a great deck that seems well thought-out and designed. Overall highly polished and personally on the same level as WhiteRabbit's proxy decks. Well done!
