Muldrotha, the Gravetide lets Eternal Witness be cast from the graveyard each turn as the creature slot; Witness returns Temporal Manipulation to hand, Ashnod's Altar sacrifices Witness for 2 colorless, and the extra turn resets Muldrotha's casting permission so the whole loop runs again. The engine runs one loop per turn cycle and locks opponents out entirely once it starts — the table sees an Eternal Witness enter, a sorcery recur, and a five-mana extra turn resolving before they get another untap step.

Cheaper, tighter, alternate lines

Time Warp is the direct swap for Temporal Manipulation — same cost, same text, same role. Phyrexian Altar can replace Ashnod's Altar if the deck needs colored mana instead of 2 colorless, though 5 mana per loop leaves little room for interaction protection, so pair this with countermagic like Swan Song or Pact of Negation to protect the Temporal Manipulation cast.
