Dark Ritual blinks Eternal Witness via Displacer Kitten, which returns the other spell; that spell blinks Eternal Witness again, which returns Dark Ritual. The loop nets mana on every Dark Ritual activation and fires infinite magecraft and ETB triggers along the way. It lives in Sultai spellslinger or reanimator shells that already run Eternal Witness as a value piece — Displacer Kitten is the only add that turns the package into a kill.

Variations

Cheaper, tighter, alternate lines

Cabal Ritual can substitute for Dark Ritual if threshold is online, netting even more mana per loop. The combo doesn't close on its own — pair it with Thassa's Oracle or Grapeshot as the terminal spell, since casting your library into an empty deck wins on the spot once mana is infinite.
