Mana Echoes + Seal of Removal + Golgari Findbroker + Mycosynth Lattice

Mana Echoes

Seal of Removal

Golgari Findbroker

Mycosynth Lattice

How it works

1. Activate Seal of Removal by sacrificing it, returning Golgari Findbroker to your hand.
2. Cast Golgari Findbroker by paying 4.
3. When Golgari Findbroker enters the battlefield, it and Mana Echoes trigger.
4. Resolve the Golgari Findbroker trigger, returning Seal of Removal from your graveyard to your hand.
5. Resolve the Mana Echoes trigger, adding at least 5.
6. Cast Seal of Removal by paying 1.
7. Repeat.
8. If you control six or more Elves and/or Shamans, this combo nets infinite mana.

This cunning loop turns the humble Golgari Findbroker into an engine of continuous recycling by leaning heavily on Mycosynth Lattice to transform every card into an artifact and unify their type lines, ensuring Mana Echoes counts a massive horde of creatures upon each entry to flood your pool with explosive amounts of mana. While the Findbroker's own triggered ability reaches into your graveyard to retrieve Seal of Removal, that very same enchantment serves as the safety valve that bounces the Shaman back to your hand, allowing you to replay it over and over again.
