Jegantha, the Wellspring + Horde of Notions + Blasting Station + Rising of the Day

Jegantha, the Wellspring

Horde of Notions

Blasting Station

Rising of the Day

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 ingenious loop turns Jegantha, the Wellspring into an infinite ammunition engine by utilizing its own strict color requirements to pay for Horde of Notions' ability. When Jegantha taps for its colorful five-mana bounty, that mana directly funds Horde of Notions to recur Jegantha from the graveyard for free. Blasting Station then converts this perpetual cycle of rebirth into lethal damage, using its sacrifice outlet to clean up Jegantha while its triggered ability untaps itself upon Jegantha's re-entry. Meanwhile, Rising of the Day quietly assists the operation by granting the necessary haste so Jegantha can tap immediately upon returning to the battlefield, ensuring the loop runs continuously without missing a beat.
