Jegantha, the Wellspring + Horde of Notions + Blasting Station + Tannuk, Steadfast Second

Jegantha, the Wellspring

Horde of Notions

Blasting Station

Tannuk, Steadfast Second

How it works

1. Activate Jegantha by tapping it, adding that cannot be spent to pay generic mana costs.
2. Activate Blasting Station by tapping it and sacrificing Jegantha.
3. Activate Horde of Notions by paying , causing you to cast Jegantha from your graveyard without paying its mana cost.
4. When Jegantha enters, Blasting Station triggers, untapping Blasting Station.
5. Repeat.

This loop transforms the colorful mana generated by Jegantha, the Wellspring into an endless cycle of sacrifice and rebirth, fueled by Blasting Station to deal infinite damage to any target. Whenever Jegantha returns to the battlefield, Blasting Station's triggered ability untaps itself, while Tannuk, Steadfast Second ensures that the returning creature immediately gains the haste it needs to tap right back into the action. Finally, Horde of Notions steps in as the engine's master, using that same exact color combination to pluck Jegantha straight from the graveyard over and over again without paying its mana cost.
