Turnabout refunds its own casting cost by untapping all lands, then Ghostly Flicker blinks Eternal Witness and Timeless Witness back to hand the spells just spent. The loop is self-contained inside blue-green: both Witnesses recur each other's targets, and every iteration fires ETB and LTB triggers for anything that cares — landfall, magecraft, or death-and-return payoffs.

Recipe

How it works

Prerequisites

Lands you control can tap to produce at least . If lands you control can tap to produce at least , this combo nets infinite mana. You can then stop casting Turnabout and blink one other permanent using Ghostly Flicker. You may also tap artifacts and/or creatures instead for mana if desired.

Steps

Activate any number of lands you control by tapping them, adding at least .
Cast Turnabout by paying , untapping all lands you control.
Cast Ghostly Flicker by paying , blinking Eternal Witness and Timeless Witness.
When Eternal Witness and Timeless Witness enter the battlefield, they trigger, returning Turnabout and Ghostly Flicker from your graveyard to your hand.
Repeat.

Result

Infinite LTB; Infinite ETB; Infinite storm count; Infinite magecraft triggers; Infinite blinking; Infinite landfall triggers; Infinite mana permanents you control can produce

Variations

Cheaper, tighter, alternate lines

Timeless Witness is the redundant Eternal Witness here; running both is what makes the loop 4-card rather than requiring a third recursion piece. Drop the floor to exactly and the combo still runs but nets zero mana per loop — add one more land that produces colorless to push it into net-positive. Pairing infinite ETB with Ruin Crab, Altar of the Brood, or Thassa's Oracle closes the game; the loop generates the triggers, not the win.
