Jegantha, the Wellspring + Horde of Notions + Viscera Seer + Anger

Jegantha, the Wellspring

Horde of Notions

Viscera Seer

Anger

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 crafty loop turns Jegantha, the Wellspring into a self-recycling engine, tapping the Elk Avatar for its exact five-color mana restriction to directly fuel Horde of Notions' activated ability. By targeting the graveyard with that massive color requirement, Horde of Notions pulls Jegantha right back onto the battlefield for free over and over again. Meanwhile, Viscera Seer acts as the necessary executioner to sacrifice Jegantha and send it back to the graveyard while filtering your draws with infinite scry triggers. The presence of Anger in your graveyard ensures that Jegantha (and any other creatures you control) instantly gains haste as long as you control a Mountain, allowing the whole loop to fire off immediately without waiting for summoning sickness.
