Displacer Kitten blinks Mnemonic Wall every time a noncreature spell resolves, and the Wall's enters-the-battlefield trigger recurs whichever ritual is sitting in the graveyard — Dark Ritual feeds back Cabal Ritual, Cabal Ritual feeds back Dark Ritual, and each pass through the loop nets positive black mana. The combo sits naturally in blue-black spellslinger or storm commanders like Kess, Dissident Mage or Inalla, Archmage Ritualist, both of whom want rituals in the graveyard anyway.

Variations

Cheaper, tighter, alternate lines

Cabal Ritual requires threshold to produce five black rather than three, so graveyard setup matters — eight or more cards in the bin before going off guarantees a wider mana margin. Any Mnemonic Wall substitute that returns an instant or sorcery on ETB, such as Archaeomancer or Salvager of Secrets, slots in if the Wall is removed, though both cost more to recast each loop. Spend the infinite mana into Brain Freeze for the kill, or pair with Thassa's Oracle as the cleaner two-card closer once the library is empty.
