# Day's Undoing Day's Undoing represents a pivotal moment in Magic design where developers pushed the boundaries of what a blue spell could accomplish. As a mythic rare from Magic Origins, it draws collector attention for its powerful effect—essentially a Time Warp variant that resets the game state. Collectors value this card for its role in competitive formats and its design significance rather than scarcity alone. Both nonfoil and foil versions circulate in the secondary market, with foils commanding premiums among players seeking premium copies. The card's mythic rarity and functional uniqueness make it a notable inclusion in collection-building, particularly for those focused on blue spells or cards with game-altering mechanics.
