Cool idea, it's always neat to see someone make a game that could be played with cards in real life.
The art is pretty cool, I like the different elements and the colors you used for them. The game could use a lot of polish with the UI and all that, but I completely understand how that can get left out when you only have 48 hours. The gameplay is interesting, but it seems a bit too RNG dependent. It would help if the element doubling worked, but the randomness of the wand makes strategy difficult. I think it would be interesting if it would shuffle the deck before each encounter and you can see what cards will be played in order. It would also be interesting if you had the ability to put one unnecessary card back in your deck during each encounter. That way you could plan the optimal order to quell the spirits.
But overall, a cool submission with a lot of potential!
