This is essentially a gotcha game on mobile. Unlike Magic Online your collection on Arena has absolutely ZERO value and is unable to be sold. You have to shovel in money to compete in a casual setting and will never be rewarded for it. Please never spend money in game and look up any promo codes to get free packs. This game could be sustainable and fair if you just could pay a subscription for access to all cards available instead of spending hundreds for a mythic.
