Ashaya, Soul of the Wild + Cloudstone Curio + Seed the Land + Phyrexian Walker

Ashaya, Soul of the Wild

Cloudstone Curio

Seed the Land

Phyrexian Walker

How it works

1. Cast Phyrexian Walker by paying 0.
2. When Phyrexian Walker enters the battlefield, Seed the Land triggers, creating a 1/1 Snake creature token.
3. When the Snake enters the battlefield, Cloudstone Curio triggers, returning Phyrexian Walker from the battlefield to your hand.
4. Repeat.

This cunning loop transforms the fragile freebie Phyrexian Walker into an engine of endless creation by leveraging Ashaya, Soul of the Wild to turn every creature you control into a Forest. Because Ashaya makes your creatures into lands, casting Phyrexian Walker instantly triggers Seed the Land to produce a Snake token, which in turn satisfies Cloudstone Curio's condition to bounce the Walker right back to your hand. Cloudstone Curio watches the incoming nonartifact permanent and uses the Snake's creature type to cleanly retrieve your zero-mana artifact creature, allowing you to replay it indefinitely.
