Wizards of the Coast is notorious for making tone-deaf, unwanted, and rushed products. Arena is no different. If you want to keep up with the hottest metas, or grind for highest ranks, you will be forking up the cash to do so. Which is only different from paper magic in that you wont actually own a copy of the card. In arena, you get nothing and you will be happy about it, because they refuse to improve as a company. Profit over customer happiness is the wotc motto.
