Jegantha, the Wellspring + Horde of Notions + Viscera Seer + Concordant Crossroads

Jegantha, the Wellspring

Horde of Notions

Viscera Seer

Concordant Crossroads

How it works

1. Activate Jegantha by tapping it, adding that cannot be spent to pay generic mana costs.
2. Activate Viscera Seer by sacrificing Jegantha.
3. Activate Horde of Notions by paying , causing you to cast Jegantha from your graveyard without paying its mana cost.
4. Repeat.

This dazzling loop hinges on Jegantha, the Wellspring providing the exact five-color mana required to activate Horde of Notions, which brings Jegantha right back from the graveyard without paying its mana cost. Viscera Seer acts as the necessary sacrifice outlet to bin Jegantha and simultaneously smooth your draws with infinite scry triggers, while Concordant Crossroads grants haste so that the recast Jegantha can be tapped immediately to start the cycle over. Because the mana produced by Jegantha, the Wellspring cannot pay generic costs, it flows perfectly into the strictly colored activation cost of Horde of Notions to create an endless engine of sacrifices, enters-the-battlefield triggers, and storm count.
