Does this really need its own thread, you can get face boosters by winning contest, donating money, etc. You can also earn single faces by meeting certain needs. You can see the requirements for single faces here : http://worldbeyblade.org/misc.php?action=help&hid=19
Face Contests, donating money, or Quest for Quetz.
