First, as far as I know there isn't an Alpha/Beta-Fray anymore - I think he was changed to Alpha/Beta/Untamed what should IMO help a lot as you can play it now with cards from the Untamed Set.
Second, there are enough cards in the rental market so IMO you or your guildmates can just rent the cards you need.
Third, you are free to suggest in discord any change you want into the DAO-section OR run your own personal proposal.
