# Shriekhorn Shriekhorn is a common from Mirrodin Besieged that appeals primarily to players building affordable mill decks rather than serious collectors. The card's straightforward effect—milling cards from libraries—made it functional in limited formats but never achieved constructed relevance. Collectors typically overlook it entirely, as commons from this era rarely hold value unless they see competitive play or possess unusual artwork. The foil variant exists but generates minimal collector interest given the card's obscurity. Shriekhorn represents the vast majority of Magic's printed commons: competent filler that served its purpose in draft environments and has since faded into bulk bins. It's the kind of card most players encounter once and forget.
