Nesting Dragon + Bladewing's Thrall + Ashaya, Soul of the Wild + Carrion Feeder

Nesting Dragon

Bladewing's Thrall

Ashaya, Soul of the Wild

Carrion Feeder

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 Carrion Feeder 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 elegant loop transforms the graveyard into an endless dragon-forging workshop by blurring the line between creatures and lands. With Ashaya, Soul of the Wild on the battlefield, Bladewing's Thrall counts as a land, meaning its entry triggers Nesting Dragon's landfall ability to hatch a Dragon Egg. You then sacrifice the Thrall to Carrion Feeder, letting the newly spawned Egg hit the battlefield and immediately return Bladewing's Thrall from the graveyard to repeat the cycle.
