As we knew that the historic format is unstable and hard to balance even with the ban system.

I would like to suggest WOTC make the new feature to the game like
VIP member, that allows players to name the card that they don't want to face in the opponent's deck in the matchmaking. Also, by doing that WOTC may charge the payment per month to those VIP member features.
It's might be the event testing before officially released.

The player can have a new experience and WOTC can gain more income to help develop the future of magic.
