Tangleroot + Words of Wind + Rograkh, Son of Rohgahh + Guardian Project

Tangleroot

Words of Wind

Rograkh, Son of Rohgahh

Guardian Project

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, Guardian Project triggers.
4. Holding priority, activate Words of Wind by paying 1, replacing the next card you draw.
5. Resolve the Guardian Project 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 free spellcasting into a devastating one-sided bounce engine by turning every card draw into a weapon. You begin by casting Rograkh, Son of Rohgahh for zero mana, which triggers Tangleroot to instantly rebate the green mana needed to activate Words of Wind. When Rograkh enters, Guardian Project sees a nontoken creature with a unique name and triggers to draw a card; by paying into Words of Wind in response, that draw is replaced with a mass bounce effect. This forces you to return Rograkh to your hand while stripping your opponents of their boards piece by piece, allowing you to replay the kobold commander endlessly to clear every permanent they control.
