Kings & Creatures

From BoardGameGeek:

Kings & Creatures is a set-collection game in which you take what you want to get what others need. All players help themselves to a heroic selection of great cards to create valuable collections - but only those who combine courageous taking with clever waiting will get hold of the most fabulous heroes. Access to grandiose cards is given only to those who choose modest cards...but those who want only to preserve their future chances with clever restraint may discover that the true heroes have long been elsewhere. -description from the publisher
