Yep.. I was always curious about that...
 
What would happen if i ever Crystalized all my cards?
A message should Appear where you can't run out of cards.. (Having at least 4 on your deck, or 10 speed) or something like that.
This is why we are here.. We are beta testers..


Well, now. Who wants to sell me some cheap cards?
Any satoshi card up to sale? lol..
