Jegantha, the Wellspring + Horde of Notions + Woe Strider + Fires of Yavimaya

Jegantha, the Wellspring

Horde of Notions

Woe Strider

Fires of Yavimaya

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 ingenious loop relies on a clever quirk of Jegantha, the Wellspring's color-intensive mana ability, which provides the exact WUBRG required to activate Horde of Notions' graveyard-recursion ability. By using Woe Strider to sacrifice Jegantha after it taps for mana, you send the legendary Elk to the graveyard just in time for Horde of Notions to pull it right back onto the battlefield for free. Fires of Yavimaya neatly ensures that Jegantha gains haste the moment it returns, allowing you to tap it immediately and repeat the cycle for an endless stream of sacrifices, death triggers, and scry activations.
