Quote from Gutterstorm »Yeah it looks like you have a pretty severe misunderstanding of what’s going on.
Rather than answer most of the questions since they hinge on a single misunderstanding I’ll just say this; the cards in the brawl precon decks, while standard legal, will not be found in draft boosters. Meaning they won’t effect prerelease, they aren’t a factor in the design choices of the set itself and the set itself is not designed to support multiplayer in any sort of special way.
Brawl is live on Arena now with a special event that allows players to play the precons.
As for the brawl like format that sounds like you’re talking about Oath Breaker.
