One more thing that makes "proxy" events even harder is Wizards changed/updated/clarified their policy on what a "proxy" is.
The definitions now are (short hand):
Proxy: Card given out by TO to replace a card damaged or unplayable in the middle of an event.
Counterfeit: Any reproduction of WotC IP (including printed out slips of paper for "old term proxy")
Playtest: A real magic card with writing on it to signify it is a different card.
As is, a WPN Store can not hold an event that allows "counterfeit" cards. We can only hold events that allow playtest cards. This essentially killed the eternal events at my store. because people were comfortable looking at a card and saying "yep, that's a Mox Ruby" instead of trying to decipher scribble on a card.
