Jegantha, the Wellspring + Horde of Notions + Phyrexian Altar + Anger

Jegantha, the Wellspring

Horde of Notions

Phyrexian Altar

Anger

How it works

1. Activate Jegantha by tapping it, adding that cannot be spent to pay generic mana costs.
2. Activate Phyrexian 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 infinite loop turns Jegantha, the Wellspring into a self-sustaining engine by exploiting its unique color-restricted mana to continuously fuel its own resurrection. With Phyrexian Altar providing a sacrifice outlet that refunds the exact colored mana needed—and also converting spare pieces into colored mana of any type—Horde of Notions can repeatedly cast Jegantha straight from the graveyard without ever running out of resources. Meanwhile, Anger rests quietly in your graveyard, granting your loop-bound commander the haste it needs to tap for its five-color bounty the very moment it hits the battlefield.
