This seems like a really fun concept! I'm enjoying but a few things to point out:
The game seems to be zoomed in, and a bit of the game gui isn't readable
When hovering over the card text for information, it's going behind other buttons (such as the card reforge button)
Some of the battle overlay appears after battle, and interacting with it crashes the game (the double down button was still appearing after battle, i pressed it and the game crashed!)
I know this is a very early build but I hope you work on it a lot, because it's very fun :)
