Surge Foil is a new type of premium foil card introduced in the Universes Beyond Warhammer 40,000 Commander Decks. They are easily identified by their rippling foil effect across the entire card, as opposed to the underprinting common to traditional foils. Surge foils are available in a number of products, including the Warhammer 40,000 Commander Decks, The Lord of the Rings: Tales of Middle-earth, and Magic: The Gathering – Doctor Who Collector Boosters. Surge foils are considered a fan favorite and are highly valued by collectors.
