Nesting Dragon + Bladewing's Thrall + Ashaya, Soul of the Wild + Troubled Healer

Nesting Dragon

Bladewing's Thrall

Ashaya, Soul of the Wild

Troubled Healer

How it works

1. Cast Bladewing's Thrall by paying 2.
2. When Bladewing's Thrall enters, Nesting Dragon triggers, as Bladewing's Thrall is a land due to Ashaya.
3. Holding priority, activate Troubled Healer by sacrificing Bladewing's Thrall.
4. Resolve the Nesting Dragon trigger, creating a 0/2 Dragon Egg creature token.
5. When the Dragon Egg enters, Bladewing's Thrall triggers, returning itself from your graveyard to the battlefield.
6. Repeat from step 2.

This clever loop turns Ashaya, Soul of the Wild into the ultimate catalyst by turning your other creatures into lands, allowing Bladewing's Thrall to double as a land whenever it enters the battlefield. That land status immediately triggers Nesting Dragon to spawn a Dragon Egg, while Ashaya ensures the Thrall itself counts as a Dragon to satisfy the Thrall's own resurrection trigger and fly safely above the fray. By using Troubled Healer to sacrifice the Thrall to its own ability, you send it straight to the graveyard so it can watch the new Egg arrive, triggering its own return to the battlefield and letting you repeat the cycle indefinitely.
