This event is a little tilting. The community wants Brawl, so WotC gives up brawl but makes it locked to two decks.
I wonder how many people will get their single win and not play the event any more. Then Wotc says "See people do not want brawl, players played very few games of it "
It would have been nice if there was two wins, one with each deck. Then after that the deck selection unlocked and we could play out brews.
