Please, don't leave formats alone, as you are doing right now. Hire people to control formats on Arena. An online game should have ban, rebalancing, and sban every month at least. On the contrary, now formats are completely lost and left to themselves. All the money you have earned from UB should you be permitted to do that. Please invest money not only in fancy alternative print of cards, but also in customer and player care. Fidelizing players and buyers is as important as bringing new people to the game.
