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

Jegantha, the Wellspring

Horde of Notions

Altar of Dementia

Anger

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 clever loop uses Jegantha, the Wellspring as both its own fuel and its own resurrection target, generating a self-sustaining cycle of sacrifice and rebirth. By tapping Jegantha for its restriction-bound five-color mana, you feed the exact color requirements needed to activate Horde of Notions, which plucks Jegantha right back out of the graveyard to cheat it onto the battlefield for free. Altar of Dementia turns this revolving door into a lethal weapon by milling your opponents for five cards with every single sacrifice. Meanwhile, Anger rests quietly in your graveyard, using its static ability to grant your looping creatures haste the moment you control a Mountain, ensuring everything runs at maximum velocity.
