If I made the deck remixable.
Rule 1: Don't make the badges free, you can change the requirements if you want to.
Rule 2: Add something to the remixed deck; add something new or change something.
Rule 3: Never steal and you're free to go.
Just remember, don't steal the blueprints and instead add a credit on the rule, since somebody can just view deck source and then find it if you stole or credited.
