Jegantha, the Wellspring + Horde of Notions + Goblin Bombardment + Garna, the Bloodflame

Jegantha, the Wellspring

Horde of Notions

Goblin Bombardment

Garna, the Bloodflame

How it works

1. Activate Jegantha by tapping it, adding that cannot be spent to pay generic mana costs.
2. Activate Goblin Bombardment 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 loop relies on Jegantha, the Wellspring to generate the exact five-color mana requirement for Horde of Notions, while Goblin Bombardment provides the free sacrifice outlet needed to put Jegantha back into the graveyard. Horde of Notions then uses that specific colored mana to replay Jegantha directly from the graveyard without paying its mana cost, completing the infinite cycle that yields endless damage and sacrifice triggers. Meanwhile, Garna, the Bloodflame sits ready in the background as a piece of this combo's broader toolkit, its flash and haste-granting abilities leveraging these repeated creature movements and deaths.
