Jegantha, the Wellspring + Horde of Notions + Blasting Station + Concordant Crossroads

Jegantha, the Wellspring

Horde of Notions

Blasting Station

Concordant Crossroads

How it works

1. Activate Jegantha by tapping it, adding that cannot be spent to pay generic mana costs.
2. Activate Blasting Station by tapping it and sacrificing Jegantha.
3. Activate Horde of Notions by paying , causing you to cast Jegantha from your graveyard without paying its mana cost.
4. When Jegantha enters, Blasting Station triggers, untapping Blasting Station.
5. Repeat.

This loop is a masterclass in recycling, fueled by Jegantha, the Wellspring tapping to produce the exact five-color mana requirement needed for Horde of Notions to cast that same elk back out of the graveyard for free. To turn this recursion into a win, Blasting Station acts as both the sacrifice outlet and the lethal damage dealer, capitalizing on its own triggered ability that untaps itself whenever Jegantha enters the battlefield anew. Meanwhile, Concordant Crossroads ensures that Jegantha gains haste immediately upon re-entering play, bypassing summoning sickness so the cycle can repeat indefinitely.
