I'm attempting to build Magic: The Gathering, but in Ruby. As a bit of Ruby practice, your task would be to find a card to implement. You can use the existing cards as examples, particularly cards like Story Keeper. 

Easy cards to implement would be these vanilla ones: https://scryfall.com/search?as=full&q=t%3Acreature+is%3Avanilla&utm_source=mci. 

If you're looking for more of a challenge, pick something from the recent set: https://scryfall.com/search?q=set%3Aone&unique=cards&as=full&order=name.

I'll pay you $2.50 for each vanilla card, and $5 for each non-vanilla card, up to a total of $50USD.
