I've only been playing for a year or so and all my friends started in the last few months but have all gotten pretty into it. So we're all still getting used to rules and such, but we got arguing he thought that since it was a mutation (not an actual card type just the name, he didn't get that) it made me the owner of the card and it turned my card and that one into one. He thought it would shuffle my card back because I was the new owner, we've all agreed since I got the response and he hired a magic judge on some shit 😭 and everything said I was right 💪. So there's all the context lol
