It's very clear that Metal is just baiting everyone into thinking he'll do a best of whatever, only so he can deliver an anti-climax and act morally superior to everyone else. I say don't get all hyped for Metal to play and lose in an irregular duel event, instead wait until he enters Masters of Arena 4, where there's an actual prize on the line (not to mention no opportunity to stream cheat). Getting knocked out of that is an event he can't pull out of!
