Ghostly Flicker blinks Eternal Witness and Greenwarden of Murasa together, letting each return one spell from the graveyard — Turnabout comes back via Eternal Witness, Ghostly Flicker comes back via Greenwarden, and Turnabout untaps all lands to fund the next iteration. The loop lives in landfall and ETB-value decks, where Tatyova, Benthic Druid or Aesi, Tyrant of Gyre Strait turns every untap cycle into additional card draw before the kill lands.

Cheaper, tighter, alternate lines

Greenwarden of Murasa is the most cuttable piece — Nissa, Steward of Elements or any redundant graveyard-return effect on an ETB body can replace it in lists that already run Eternal Witness heavily. The infinite mana closes with Blue Sun's Zenith to mill the table or Walking Ballista for direct damage; without a sink in hand the loop stalls out as a storm count engine.
