Tangleroot + Words of Wind + Phyrexian Walker + Kindred Discovery

Tangleroot

Words of Wind

Phyrexian Walker

Kindred Discovery

How it works

1. Cast Phyrexian Walker by paying 0.
2. Tangleroot triggers, adding .
3. When Phyrexian Walker enters the battlefield, Kindred Discovery triggers.
4. Holding priority, activate Words of Wind by paying 1, replacing the next card you draw.
5. Resolve the Kindred Discovery trigger, causing you to return Phyrexian Walker from the battlefield to your hand, and causing each opponent to return a permanent they control from the battlefield to your hand.
6. Repeat.

This elegant loop turns the zero-mana cost of Phyrexian Walker into a relentless engine of disruption. Each time you cast the artifact creature, Tangleroot provides the green mana needed to activate Words of Wind, which replaces the card draw you would normally get from Kindred Discovery. Because Kindred Discovery triggers upon the Walker entering the battlefield as your chosen creature type, its replacement effect forces you to bounce the Phyrexian Walker right back to your hand while systematically stripping your opponents of every permanent they control.
