Jegantha, the Wellspring + Horde of Notions + Goblin Bombardment + Dragonlord Kolaghan

Jegantha, the Wellspring

Horde of Notions

Goblin Bombardment

Dragonlord Kolaghan

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 ingenious loop turns Jegantha, the Wellspring into an endlessly recurring engine, utilizing its own tap ability to fuel the very activation cost required to get it back. Because Jegantha's mana restriction specifies that it cannot pay generic mana costs, Horde of Notions provides the exact five-color colored mana sink needed to bypass that restriction and cast Jegantha straight from your graveyard without paying its mana cost. Meanwhile, Goblin Bombardment acts as both the necessary sacrifice outlet to send Jegantha to the graveyard and the ultimate win condition, converting each iteration into infinite damage for your opponents. Though Dragonlord Kolaghan sits alongside them in the deck, the core engine effortlessly loops through these colored mana requirements, death triggers, and damage steps to overwhelm the table.
