Hate to be a buzz kill but i cant stop my self from mentioning; if everyone on ur gets stuff from the calender, then it is worthless as inflation will just happen. eg giving everyone 30clintz does not mean every one is richer, it merely means everyone has 30 more clintz so clintz lose 30 clintz value. much like inflation in the real world, printing money does not make every one richer it just means theres more of it, remember money itself is worthless so giving every one money will just make the value of clint drop and consequently prices of cards will rise . MONEY IS A PROMISE THAT ITS WORTH X AMOUNT, WHEN theres more actual money prices GO UP TO..
...30 clintz is nothing really. You can't do much with it, at most I see the advent calendar giving out 500 clintz total by the time the advent calendar is done. That again is nothing and barely enough to buy a cheap decent common card. 30 clintz barely creates any inflation, you can't apply most real life economic concepts onto virtual currency like UR.
