This clever loop is anchored by Sekki, Seasons' Guide, which starts the chain by heading straight into Ashnod's Altar to fuel its sacrifice outlet while triggering a cascade of value. As Sekki hits the graveyard, One with the Kami sees its death and generously rewards you with a massive swarm of 1/1 Spirit tokens—scaling directly off Sekki's massive power—and generating a steady stream of colorless mana from the Altar along the way. Finally, those very same Spirit tokens can be cashed in to activate Sekki's own resurrection ability, bringing it right back to the battlefield so you can repeat the whole cycle endlessly for infinite death triggers, enter-the-battlefield effects, and colorless mana.
