Phyrexian Altar converts Eternal Witness into a black mana, which pays for Unearth; Unearth returns Eternal Witness, and Eternal Witness returns Unearth to hand. The loop closes on itself indefinitely, requiring no external mana beyond the first black — any black-green deck running sacrifice payoffs like Zulaport Cutthroat, Blood Artist, or Mayhem Devil converts this into a table kill.

Cheaper, tighter, alternate lines

Reassembling Skeleton replaces Eternal Witness if the graveyard recursion half is all that's needed, but loses the Unearth self-sufficiency — the Witness version is tighter because it recycles its own enabler. Add Altar of Dementia to mill out the table or Impact Tremors for the damage-based kill; the loop is infinite but needs a payoff on board to end the game.
