Prize List & Vault Key List
There are currently 291 prizes on the Mystery Box Prize List. There are currently 38 keys hidden inside the Vault. (Keys unlock doors inside the Vault.)I'd love to participate but am currently detaching myself from the website of Cardsmith on account of the Owner's behaviors and policies.
If I can still play, submitting designs made locally using MSE, I'd like a box! (Hopefully I'm notified when you respond, I haven't been getting emails from notifications I should be lately...)
