Jegantha, the Wellspring + Horde of Notions + Bloodflow Connoisseur + Thousand-Year Elixir

Jegantha, the Wellspring

Horde of Notions

Bloodflow Connoisseur

Thousand-Year Elixir

How it works

1. Activate Jegantha by tapping it, adding that cannot be spent to pay generic mana costs.
2. Activate Bloodflow Connoisseur 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 intricate loop relies on Jegantha, the Wellspring to generate the exact five-color mana required to fuel Horde of Notions, which acts as a recurring engine to cast Jegantha straight out of your graveyard without paying its mana cost. Because Jegantha's mana restriction specifies that it cannot pay generic mana costs, Horde of Notions's ability handles the heavy lifting by covering the entirety of the cost using that exact color combination. Meanwhile, Bloodflow Connoisseur provides a reliable sacrifice outlet to send Jegantha back to the graveyard to restart the cycle, rewarding your endless loop with a massive, growing pile of +1/+1 counters on the Connoisseur. While Thousand-Year Elixir isn't explicitly required for this specific graveyard-to-battlefield loop, its passive ability to let creatures ignore summoning sickness and its untap utility fit right into the toolbox of an elemental-heavy strategy.
