Toph, the First Metalbender turns Staff of Domination into a Swamp, and Urborg, Tomb of Yawgmoth makes that land tap for black mana. Mirari's Wake doubles that mana output so each tap produces two black, one of which pays back Staff of Domination's one-mana untap cost and leaves the loop self-sustaining. The combo slots into Naya goodstuff or combo-control shells that can already justify running Mirari's Wake as a standalone anthem.

Variations

Cheaper, tighter, alternate lines

Magus of the Vineyard or any other passive mana doubler doesn't substitute cleanly here — Mirari's Wake is doing double duty as a pump piece and the cost-reduction engine, so swapping it breaks the math. Once the loop is live, tap Staff of Domination to draw your entire library and close with whatever payoff the Naya color identity permits — Aetherflux Reservoir built in through lifegain triggers or a hardcast Walking Ballista both seal the game.
