Physical cards wouldn't really work due to copyright. As unfair as it seems, Nintendo could possibly sue for infringement due to giving away work that isn't by Nintendo. Also, think of all the paper needed :c All the trees killed.
So you are completely caught up?
Coders may have to design a system for:
Trading
Buying
Selling
A system would be cool! What would selling be like though? Real money is out of the question.
That would be awesome! People can buy things without using actual money! Plus we can't get sued![]()
