An Ampersand Foil is a unique promo released for certain Rare and Mythic Rare cards from Adventures in the Forgotten Realms. They were released in very limited numbers to WPN Premium stores, meaning there is a limited number of them in existence.
 
Ampersand Foil cards feature a traditional foil treatment with a glossy D&D ampersand overlaying the entire card. These cards are, as noted, exceptionally rare and are particularly loved by collectors due to their nature as crossover highlights. The D&D ampersand is itself a cool-looking symbol, but fans of both Wizards of the Coast IPs can take some substantial pleasure in collecting these special cards.
