@TheEmu Yes, all things could be bought with the Joker but why? There's only one thing with scarcity value, the SE cards. That value is artificial, and it's designed that way on purpose to incentivize purchases, either of 30 cards you were unsure of, or gambling. This can easily be seen in the conversations on the boards about the process, where nobody says "I'm so lucky to have won a Melissa card." If they're excited enough to write aboout it, it's because they won an SE card or a Joker. Those have rarity. Just like good loot in a loot box.
You get that, right? I'm not talking about a hypothetical future where a month from now I really wish I'd bought the advent calendar. I'm talking about the actual present where people are gambling for past and present SE cards and Jokers. It's very obvious that while some people are enjoying the endorphin rush of the game, others are with the hope /disappointment of getting/not-getting those cards.
