Jegantha, the Wellspring + Horde of Notions + Goblin Bombardment + Samut, Voice of Dissent

Jegantha, the Wellspring

Horde of Notions

Goblin Bombardment

Samut, Voice of Dissent

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 a clever workaround to Jegantha, the Wellspring's color restriction, since its ability produces a rigid five-color mana payload ({W}{U}{B}{R}{G}) that cannot pay generic costs. By channeling that exact color requirement directly into Horde of Notions, you can bypass the mana value restriction entirely to recast Jegantha straight from your graveyard after it meets its demise. Goblin Bombardment provides the necessary sacrifice outlet to bin Jegantha while turning each iteration of the loop into lethal direct damage. Meanwhile, Samut, Voice of Dissent stands ready in the wings with flash, double strike, and haste, granting your board extra speed and an untap option if needed while the elemental graveyard engine hums along.
