Turnabout untaps all lands to refund the mana spent on both spells; Ghostly Flicker then blinks Mnemonic Wall and Eternal Witness, which return Turnabout and Ghostly Flicker respectively to hand, resetting the loop. The table sees a Simic value shell that suddenly fires off infinite landfall, infinite magecraft, and infinite storm count the moment a pilot taps into the threshold mana — typically 5UUU to net positive each cycle.

Cheaper, tighter, alternate lines

Archaeomancer slots directly in for Mnemonic Wall if wall-typing matters or if a tighter curve is wanted, returning any instant or sorcery on ETB the same way. For the kill, Aetherflux Reservoir wins off storm count, Tatyova, Benthic Druid draws the library off landfall, and Walking Ballista drains the table off the infinite colorless — pick whichever already fits the shell.
