Concordant Crossroads

How it works

1. Activate Jegantha by tapping it, adding that cannot be spent to pay generic mana costs.
2. Activate Umbral Collar Zealot 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 loop turns Jegantha, the Wellspring into a self-recycling engine, generating an endless stream of sacrifice and entry triggers. By tapping Jegantha, the Wellspring for its restrictive five-color mana, you provide the exact color requirements needed to fund Horde of Notions's activated ability. Umbral Collar Zealot acts as the necessary exit strategy, letting you sacrifice Jegantha, the Wellspring while simultaneously setting up your draws through its surveil ability. Finally, Concordant Crossroads ensures that Jegantha, the Wellspring gains haste immediately upon returning to the battlefield, allowing it to tap for mana again right away and keep the cycle spinning infinitely.
