Jegantha, the Wellspring + Horde of Notions + Phyrexian Altar + Kratos, God of War

Jegantha, the Wellspring

Horde of Notions

Phyrexian Altar

Kratos, God of War

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.

This marvelous loop revolves around Jegantha, the Wellspring, which provides the exact five-color mana restriction needed to feed Horde of Notions' recursive activation cost. By tapping Jegantha for its colored mana and immediately sacrificing it to Phyrexian Altar, you generate a mana of any color while moving Jegantha into the graveyard as an Elemental. Horde of Notions then uses that very mana to pull Jegantha right back onto the battlefield, letting you repeat the cycle indefinitely. Meanwhile, Kratos, God of War grants haste to keep your loop fluid from the moment Jegantha re-enters, while also ensuring your opponents face a ticking clock of punishment for any creatures they fail to send into battle.
