I’m sorry, what is your point? Every medal is number of scoops you get and card planning plus card luck.

If anything a destruction medal would be the least earned “accidental” medal. There are medals every single week that happen in brackets where absolutely no one is playing. Some random person takes max and fav flava because they used their visits – there was zero game play. It would be impossible for a person to just sit there doing nothing and get a destruction based medal. They would have to actively choose to purchase cards.

Also, it would be far from safest as a medal. You can know what you’ve done in a week, but it would be pretty impossible to judge what other players have done.
