Jegantha, the Wellspring + Horde of Notions + Shilgengar, Sire of Famine + Rising of the Day

Jegantha, the Wellspring

Horde of Notions

Shilgengar, Sire of Famine

Rising of the Day

How it works

1. Activate Jegantha by tapping it, adding that cannot be spent to pay generic mana costs.
2. Activate Shilgengar 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 relies on Jegantha, the Wellspring generating the exact five-color mana requirement—{W}{U}{B}{R}{G}—needed to fuel Horde of Notions' activated ability, which brings Jegantha right back from the graveyard. Shilgengar, Sire of Famine acts as the sacrificial engine that enables this recursive cycle while churning out Blood tokens with every iteration. Meanwhile, Rising of the Day ensures that Jegantha enters the battlefield with haste so it can be tapped immediately for mana without waiting for summoning sickness.
