It would be cool if the card team put out actual limited number cards if that's even possible, otherwise I can't see any card being too rare based on the ISFL model.  Let's say that they do some sort of special rare MVP card for this season, I'm going to say that it will be Matt Kholin's card since he is killing it right now in his last season before hitting 15% regression.  Hopefully he can keep it up and then all the collectors will want his card @Kalakar
