# Knife Knife represents a curious footnote in Magic's history as a token card from Ravnica: Clue Edition, an Un-set released in 2018. Collectors view it primarily through the lens of completionism rather than constructed playability. The card exists to support the set's investigation mechanic, where clue tokens become relevant game pieces. Most collectors pursuing this card do so to complete their Un-set collections, as these supplemental sets attract players interested in silver-bordered novelties and mechanical experimentation. The uncommon rarity and nonfoil-only availability make it straightforward to acquire. Its appeal lies entirely in set completion and the broader appeal of Un-sets as collectible oddities rather than any inherent card power or scarcity.
