This is a fun project I've been working on recently. The idea of the cards started when I saw how an AI could generate realistic portraits of people. I tried to apply similar techniques to generating fantasy characters, and got amazing results.
The next 2 weeks were spent on designing the card assets, hero traits and descriptions. I borrowed some ideas from D&D (attribute points and alignment). Also threw in a random name generator, of which the names were scraped all over the internet.
Once I had the card assets, the rest all fell in place. It was obvious that the Ethereum blockchain was the best market place for such a collectible game. I spent the next 2 weeks writing the smart contract (based on ERC 721) and various pieces to support trading on the site. Fun fact: ETH price took off right before I was ready to deploy the contract on the mainnet. Due to high gas price, I had to spent a fortune... not fun!
I had a lot of fun working on it. Let me know if you have any questions.
Can you share a bit more about the art generation? Are you using StyleGAN or some other architecture? Are you hand-selecting the art from among generated images? What training dataset did you use or create?
For training, I spent a lot of time scraping images. I couldn't find any good dataset for this purpose. Controlling for quality is pretty tough, and I didn't spend nearly as much time as I should. And it's evident in the result. Some of the generated arts have pretty low pixel quality if you look at the original image. Luckily, it looks ok on the cards.
With that said, some of the l2 on ethereum is quite promising. I personally like xDai, though it is still in beta it has quite a few projects on top of it, I might use it for a few idea's I have as well. https://www.xdaichain.com/
zkRollups are also super promising. These guys look promising: https://zksync.io/
Anyways, I really like the idea. As a gan artist myself, I have had a similar idea, but more revolving around real life sports athletes.. problem is copyright would bite me in the ass real hard.
