Jegantha, the Wellspring + Horde of Notions + Phyrexian Altar + Fires of Yavimaya

Jegantha, the Wellspring

Horde of Notions

Phyrexian Altar

Fires of Yavimaya

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 brilliant loop transforms Jegantha, the Wellspring into an endless engine of rebirth, utilizing its own restrictive colored mana production to pay for Horde of Notions' incredible ability. Because Jegantha's mana can't pay for generic costs, Horde of Notions' exact five-color activation requirement is uniquely suited to feed on it, pulling Jegantha right back from the graveyard for free every single cycle. Meanwhile, Phyrexian Altar acts as the sacrificial catalyst that turns this relentless cycle into a self-sustaining loop while generating endless colored mana and death triggers. To ensure the process can start instantly without summoning sickness, Fires of Yavimaya grants your resurrected creature haste the moment it returns to the battlefield.
