Jegantha, the Wellspring + Horde of Notions + Viscera Seer + Urabrask the Hidden

Jegantha, the Wellspring

Horde of Notions

Viscera Seer

Urabrask the Hidden

How it works

1. Activate Jegantha by tapping it, adding that cannot be spent to pay generic mana costs.
2. Activate Viscera Seer 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 ingenious loop relies on Jegantha, the Wellspring to both fund its own resurrection and provide the colored mana required by Horde of Notions' ability, which bypasses mana costs to pull Jegantha straight back from the graveyard. Because Viscera Seer lets you seamlessly sacrifice Jegantha to the graveyard at will, you can repeat this cycle indefinitely to trigger countless enters-the-battlefield, leaves-the-battlefield, and death events. Meanwhile, Urabrask the Hidden ensures your resurrected creature gains immediate haste to tap right back for mana, while its passive ability locks down your opponents' incoming creatures.
