MTG Arena should add a sealed league. The participants would use gems/gold to enter like any sealed event. They'd be given six sealed packs to construct their deck. They would play the best of 3 rounds. Their record and deck would persist to next week, at which time, they will receive three additional packs to add to their sealed pool. They will play the best of three once again. Their record and pool of cards will persist to the next week. A league could be four weeks long and at the end prizes are rewarded based on your total win/lose ratio. At any time, someone could forfeit their league standings to reregister/pay for a new sealed pool.
