Displacer Kitten + Mana Echoes + Emeritus of Truce // Swords to Plowshares + Urn of Godfire

Displacer Kitten

Mana Echoes

Emeritus of Truce // Swords to Plowshares

Urn of Godfire

How it works

1. Cast the copy of Swords to Plowshares from exile by paying its mana cost.
2. When you cast that spell, Displacer Kitten triggers, flickering Emeritus of Truce.
3. When Emeritus of Truce // Swords to Plowshares enters, it and Mana Echoes triggers.
4. Resolve the Emeritus of Truce trigger, causing an opponent to create a 1/1 Inkling creature token with flying and preparing Emeritus of Truce.
5. Resolve the Mana Echoes trigger, adding at least CC since Displacer Kitten and Emeritus of Truce are both Cats.
6. Resolve Swords to Plowshares, exiling a creature an opponent controls and causing them to gain life.
7. Activate Urn of Godfire by paying 2, adding one colored mana.
8. Repeat any number of times.
9. If the board state allows, create an Inkling token in step 4 instead of targeting an opponent.

This elegant loop turns the recursive casting of Swords to Plowshares into a self-sustaining engine. Whenever you cast the spell, Displacer Kitten's avoidance ability triggers to blink Emeritus of Truce, which in turn triggers Mana Echoes to generate plenty of colorless mana alongside Urn of Godfire's colored mana contribution. Because both the Kitten and the Emeritus share the Cat creature type, Mana Echoes scales its mana production exponentially as the loop progresses. This allows you to continuously recast the copy of Swords to Plowshares while churning out an endless army of Inkling creature tokens and generating infinite mana and effects.
