Jegantha, the Wellspring + Horde of Notions + Viscera Seer + Mass Hysteria

Jegantha, the Wellspring

Horde of Notions

Viscera Seer

Mass Hysteria

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 dazzling loop turns Jegantha, the Wellspring into a self-recycling engine, fueled directly by its own restrictive mana ability to cover the exact colored cost required by Horde of Notions. Since Mass Hysteria grants all creatures haste, Jegantha is immediately ready to tap for mana the moment it re-enters the battlefield from the graveyard. Viscera Seer neatly dispatches Jegantha to the graveyard while letting you scry through your library, perfectly setting up the Horde to cast the companion again and again.
