Jegantha, the Wellspring + Horde of Notions + Phyrexian Altar + Dragonlord Kolaghan

Jegantha, the Wellspring

Horde of Notions

Phyrexian Altar

Dragonlord Kolaghan

How it works

1. Activate Jegantha by tapping it, adding that cannot be spent to pay generic mana costs.
2. Activate Phyrexian Altar 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.

By tapping Jegantha, the Wellspring, you generate the exact five-color mana requirement needed to fund Horde of Notions' activated ability. Sacrificing Jegantha to Phyrexian Altar lets you convert that legendary elk into the specific mana needed to recast it from the graveyard with Horde of Notions, while Dragonlord Kolaghan’s presence ensures your key pieces can return instantly to the fray. Because Jegantha's mana cannot pay generic costs, feeding it directly into the Altar and the Horde creates a self-sustaining loop that infinitely recycles your elementals and triggers every sacrifice and death effect you could ever desire.
