Jegantha, the Wellspring + Horde of Notions + Samut, Voice of Dissent + Phantom Train

Jegantha, the Wellspring

Horde of Notions

Samut, Voice of Dissent

Phantom Train

How it works

1. Activate Jegantha by tapping it, adding that cannot be spent to pay generic mana costs.
2. Activate Phantom Train 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 clever loop centers around Phantom Train acting as a sacrifice outlet to continually bin Jegantha, the Wellspring. Once Jegantha is in the graveyard, Horde of Notions steps in to cast it straight back to the battlefield for free, fueled entirely by the five-color mana produced by tapping Jegantha itself. While Samut, Voice of Dissent doesn't partake directly in this specific mechanical loop, its presence highlights the wild elemental synergies available in decks that can support this colorful engine.
