Very good point. As a long long time MTG player, I'd rather just play MTG. Granted I play paper, so having other digital card games is fun as well.
The cool thing about the ETH transactions is that at least you don't HAVE to claim all your cards. Like if you have a bunch of worthless jank, you don't need to spend the time claiming it. (IIRC they were working on a way or already implemented a way to claim all your cards in bulk.)
