# Temporal Mastery Temporal Mastery represents a significant reprint moment for collectors. Originally from Avacyn Restored, this mythic rare offers an extra turn at instant speed, making it mechanically powerful and format-relevant. The Modern Masters 2017 version matters because it provided broader access to a card that had become expensive on the secondary market. Collectors typically view this printing as a practical acquisition point rather than a chase card. The foil variant commands a modest premium, though neither version holds the scarcity of the original printing. Most collectors seeking Temporal Mastery prioritize playability over rarity, making this reprint a sensible choice for those building constructed decks without premium investment concerns.
