Jegantha, the Wellspring + Horde of Notions + Woe Strider + Anger

Jegantha, the Wellspring

Horde of Notions

Woe Strider

Anger

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 turns the five-color ability of Horde of Notions into an engine for infinite recursion by continually pulling Jegantha, the Wellspring straight out of the graveyard. Woe Strider acts as the necessary sacrifice outlet, sending Jegantha to the bin while setting up a recurring source of scry triggers along the way. Because Anger sits quietly in your graveyard granting haste as long as you control a Mountain, Jegantha is immediately ready to tap the moment it returns to the battlefield, producing the exact colorful mana required to fund Horde of Notions' activation cost over and over again.
