Tangleroot + Words of Wind + Rograkh, Son of Rohgahh + Soul of the Harvest

Tangleroot

Words of Wind

Rograkh, Son of Rohgahh

Soul of the Harvest

How it works

1. Cast Rograkh either from your hand or from the command zone by paying 0 plus commander tax, if applicable.
2. Tangleroot triggers, adding .
3. When Rograkh 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 Rograkh 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 the zero-mana cost of Rograkh, Son of Rohgahh into a relentless engine by leveraging the passive mana generation of Tangleroot to fund the activation of Words of Wind. As you repeatedly recast your free commander, Soul of the Harvest triggers to draw you a card, which Words of Wind cleverly converts into a mass-bounce effect that clears your opponents' boards of every single permanent they control. Because Tangleroot refunds the green mana needed to pay for Words of Wind's replacement effect every single time a creature is cast, you can repeat this cycle infinitely to completely lock down the game.
