Hmmm maybe the "I would love to try this card" is what gives it it's value rather than it's effectiveness alone. Could be but for me being able to try out a card would make me buy more cards because I would be sure I will use them well. But the effective cards like pyramid warden for example won't lose their value just because people can try them they will still be effective and demanded on the real server. Maybe there is a psychological side to it that I do not see idk :p
