most horrible and player unfriendly monetization model I have ever seen. If you come back after not playing for 6 months, you're so far behind on cards, you'd need to either grind for weeks (or even months) or spend way too much money to have a competetive deck again, because you can't disenchant/dust/whatever old cards you don't need anymore

But also Magic the Gathering is really fucking fun and this is often the most convenient way to play it
