Jegantha, the Wellspring + Horde of Notions + Ashnod's Altar + Concordant Crossroads

Jegantha, the Wellspring

Horde of Notions

Ashnod's Altar

Concordant Crossroads

How it works

1. Activate Jegantha by tapping it, adding that cannot be spent to pay generic mana costs.
2. Activate Ashnod's Altar 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 clever loop transforms Jegantha, the Wellspring into an endless cycle of sacrifice and resurrection, utilizing Ashnod's Altar to turn each iteration into a pair of colorless mana while feeding your death and sacrifice triggers. Horde of Notions steps in as the engine's orchestrator, using the exact color combination produced by Jegantha, the Wellspring to instantly drag our companion back from the graveyard onto the battlefield without paying its mana cost. Thanks to Concordant Crossroads granting all creatures haste, the newly returned Jegantha is immediately ready to tap and produce its restricted five-color mana once more, keeping the loop going indefinitely.
