Jegantha, the Wellspring + Horde of Notions + Woe Strider + The Fire Crystal

Jegantha, the Wellspring

Horde of Notions

Woe Strider

The Fire Crystal

How it works

1. Activate Jegantha by tapping it, adding that cannot be spent to pay generic mana costs.
2. Activate Woe Strider 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 is brilliantly fueled by Jegantha, the Wellspring, whose tap ability conveniently provides the exact five-color mana requirement needed to activate Horde of Notions. By using Woe Strider to sacrifice Jegantha, you send it straight to the graveyard, where Horde of Notions can immediately drag it back to the battlefield for free. Meanwhile, Woe Strider's sacrifice outlet rewards you with endless scry triggers, and while The Fire Crystal's token-copy and cost-reduction abilities aren't strictly necessary for the core loop, its static haste grant ensures your endlessly recurring Jegantha is always ready to tap the moment it returns.
