Can local game stores sell or give out Nexus Night promo cards (specifically as tournament prizes) if a player donates them back to the store?

Ruling: Yes, once a Nexus Night promo pack has been given away as a prize, it becomes the property of that person who can sell it or give it back to the store. The store can then use those individual cards however they want, including as tournament prizes.

Nuances:

• Stores are NOT allowed to open the promo packs themselves and sell the individual cards directly
• Stores are NOT allowed to sell the unopened promo packs
• Only cards that have been given back to the store by players (after the packs were legitimately awarded) can be resold or given away by the store
