Mana Echoes + Seal of Removal + Golgari Findbroker + Chromatic Orrery

Mana Echoes

Seal of Removal

Golgari Findbroker

Chromatic Orrery

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 clever loop transforms a humble Elf Shaman into a self-sustaining engine by exploiting the explosive mana-generation of Mana Echoes whenever Golgari Findbroker enters the battlefield. With Chromatic Orrery sitting on the board, you can freely filter your newly generated colorless mana into any color while also making use of its passive ability to spend mana as though it were any type. Meanwhile, the triggered ability of Golgari Findbroker continuously returns Seal of Removal from your graveyard to your hand each time it loops back through, letting you bounce and recast the Findbroker indefinitely to fuel the entire sequence.
