Ghostly Flicker blinks Donnie & April, Adorkable Duo and Eternal Witness together; Eternal Witness returns Ghostly Flicker and Donnie & April's trigger returns Turnabout, which untaps all lands to refund the loop's cost. The engine sits in Simic and slots cleanly into any landfall commander — Aesi, Tyrant of Gyre Strait and Tatyova, Benthic Druid both close the game on infinite landfall without a secondary piece.

Cheaper, tighter, alternate lines

Naru Meha, Master Wizard replaces Donnie & April as the Ghostly Flicker recurrence piece in lists that prefer a single-card utility body. The loop needs a kill on resolution — Aetherflux Reservoir, Walking Ballista cast off the infinite mana, or any ETB damage effect all close cleanly; the engine itself doesn't win on its own.
