Jegantha, the Wellspring

Horde of Notions

Bartolomé del Presidio

Dynaheir, Invoker Adept

How it works

1. Activate Jegantha by tapping it, adding that cannot be spent to pay generic mana costs.
2. Activate Bartolomé del Presidio 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 relies on Jegantha, the Wellspring generating the exact five-color mana requirement needed to fund Horde of Notions' activated ability, which brings Jegantha right back from the graveyard for free. To feed this endless cycle, Bartolomé del Presidio acts as the designated sacrifice outlet, allowing you to bin Jegantha while stacking up endless +1/+1 counters in the process. Meanwhile, Dynaheir, Invoker Adept sits quietly on the board, granting her haste-enabling support to your other creatures so they are primed and ready for action the moment they hit the battlefield.
