Wow, this sounds great!! I love when cards can be used in multiple ways, and this takes it to the max! [80's guitar riff, explosion]
I also really like the experimentation in how to cost and provide content. That was a big inspiration for me going into this: How can we get and give the CCG experience without having to pay rent to our random foil dealers every week? Making all non-rares PWYW is super intriguing... Just make sure you're aware of any content rights that TGC might impose. But I'm excited to see where you take this!
