This is a cool concept for the game jam. You managed to get a lot of cards and mechanics created in a short time, well done! We didn't have time to get relics implemented for ours
My only feedback would be that it is very small and hard to read in the browser, so it probably just needs to be all scaled up a little bit.
We also created a card game/deck-builder for the jam, so would love your feedback too if you want to give it a try!
