Jegantha, the Wellspring + Horde of Notions + Altar of Dementia + Gimli's Reckless Might

Jegantha, the Wellspring

Horde of Notions

Altar of Dementia

Gimli's Reckless Might

How it works

1. Activate Jegantha by tapping it, adding that cannot be spent to pay generic mana costs.
2. Activate Altar of Dementia 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 looping masterpiece relies entirely on the colored mana restrictions of Jegantha, the Wellspring being neatly bypassed by Horde of Notions, which casts Jegantha directly from the graveyard using that exact five-color mana string without needing to pay any generic costs. Each iteration of this cycle is fueled by tapping Jegantha for its vibrant mana, which is then fed into Altar of Dementia to sacrifice Jegantha and grind through your deck via mill triggers. Meanwhile, Gimli's Reckless Might sits passively granting haste to ensure your pieces are ready for action, rounding out a self-sustaining engine that endlessly recycles your companion elemental for infinite sacrifices and storm count.
