Jegantha, the Wellspring + Horde of Notions + Woe Strider + Mass Hysteria

Jegantha, the Wellspring

Horde of Notions

Woe Strider

Mass Hysteria

How it works

1. Activate Jegantha by tapping it, adding that cannot be spent to pay generic mana costs.
2. Activate Woe Strider 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 Horde of Notions and its ability to pull elementals directly from the graveyard, using Jegantha, the Wellspring as the perfect recurrable target since Jegantha itself is an Elemental. To sustain this cycle, Woe Strider steps in to cleanly sacrifice Jegantha while providing a steady stream of sacrificial fodder and bonus scry triggers through its escape and goat-creating abilities. Meanwhile, Mass Hysteria grants the necessary haste to Jegantha the moment it enters the battlefield, allowing its restrictive five-color mana ability to be tapped immediately to pay for Horde of Notions' activation cost.
