Tangleroot + Words of Wind + Phyrexian Walker + Soul of the Harvest

Tangleroot

Words of Wind

Phyrexian Walker

Soul of the Harvest

How it works

1. Cast Phyrexian Walker by paying 0.
2. Tangleroot triggers, adding .
3. When Phyrexian Walker enters the battlefield, Soul of the Harvest triggers.
4. Holding priority, activate Words of Wind by paying 1, replacing the next card you draw.
5. Resolve the Soul of the Harvest 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 loop turns a single green mana and a zero-mana artifact creature into a devastating one-sided board wipe. By casting Phyrexian Walker for free, you trigger Tangleroot to refund the green mana required to activate Words of Wind. As Soul of the Harvest's triggered ability tries to draw you a card, Words of Wind replaces that draw by forcing every player to bounce a permanent—allowing you to scoop up Phyrexian Walker right back into your hand while stripping your opponents of their lands and board state entirely.
