Displace blinks Eternal Witness and Peregrine Drake simultaneously; Witness returns Displace to hand while Drake untaps five lands, refunding the 3U cost and leaving mana to spare once five lands are in play. The combo fires at instant speed, which means it can be assembled mid-combat or in response to a boardwipe that hasn't resolved yet — a meaningful edge over sorcery-speed lines.

Variations

Cheaper, tighter, alternate lines

Ghostly Flicker is the direct swap for Displace and the more common include since it also targets artifacts and enchantments, making it easier to recur with Witness alone. Cloud of Faeries or Great Whale can substitute for Peregrine Drake as the land-untapping piece if redundancy matters. Once the loop is live, Walking Ballista or Blue Sun's Zenith converts the infinite mana into a kill — the engine alone wins nothing.
