Haakon, Stromgald Scourge + Morophon, the Boundless + Nameless Inversion + Birgi, God of Storytelling // Harnfel, Horn of Bounty

Haakon, Stromgald Scourge

Morophon, the Boundless

Nameless Inversion

Birgi, God of Storytelling // Harnfel, Horn of Bounty

How it works

1. Cast Nameless Inversion from your graveyard, as it is a Knight card, by paying 1 due to Morophon.
2. Birgi triggers, adding .
3. Resolve Nameless Inversion, giving a creature +3/-3 until end of turn.
4. If the creature has toughness 0 or less, the creature dies as a state-based action.
5. Repeat as desired.

This clever engine turns your graveyard into an infinite execution chamber by leveraging Morophon, the Boundless to completely wipe away the colored mana requirement of Nameless Inversion. Because Morophon makes your chosen creature type's spells cost {W}{U}{B}{R}{G} less, and Nameless Inversion is a Changeling that counts as every creature type (including a Knight), its cost is reduced to just a generic {1}. With Haakon, Stromgald Scourge granting you the ability to cast those Knight spells directly from your graveyard, you can loop the removal spell endlessly. Meanwhile, Birgi, God of Storytelling sits on the battlefield to generate a steady stream of red mana with every iteration, ensuring you never run out of the gas needed to keep casting the Inversion over and over again until every opposing creature's toughness is reduced to zero.
