Ashaya, Soul of the Wild + Celestial Dawn + Emeria Shepherd + Thaumatog

Ashaya, Soul of the Wild

Celestial Dawn

Emeria Shepherd

Thaumatog

How it works

1. Cast any creature by paying its mana cost.
2. When the creature enters as a Plains due to Ashaya and Emeria Shepherd, Emeria Shepherd triggers.
3. Holding priority, activate Thaumatog by sacrificing the creature cast in step 1.
4. Resolve the Emeria Shepherd trigger, returning another creature from your graveyard to the battlefield.
5. Repeat from step 2.

This loop transforms your battlefield into an engine of endless recursion by layering static type transformations with graveyard triggers. Thanks to Ashaya, Soul of the Wild, every nontoken creature you cast immediately enters the battlefield as a Forest, which Celestial Dawn then turns into a Plains. This neat color-pie trick ensures that whenever you deploy a creature, Emeria Shepherd's landfall ability sees it enter as a Plains and triggers its most powerful clause: returning a nonland permanent card straight to the battlefield instead of your hand. Before that trigger resolves, you sacrifice the newly entered creature to Thaumatog, fueling its sacrifice ability while feeding the loop. You can then endlessly recur any creature card from your graveyard, generating infinite sacrifice, death, and landfall triggers along the way.
