Tangleroot + Words of Wind + The Great Henge + Kobolds of Kher Keep

Tangleroot

Words of Wind

The Great Henge

Kobolds of Kher Keep

How it works

1. Cast Kobolds of Kher Keep by paying 0.
2. Tangleroot triggers, adding .
3. When Kobolds of Kher Keep enters the battlefield, The Great Henge triggers.
4. Holding priority, activate Words of Wind by paying 1, replacing the next card you draw.
5. Resolve the The Great Henge trigger, causing you to return Kobolds of Kher Keep 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 clever loop relies on free creature spells to generate a self-sustaining engine of mana and disruption. By casting Kobolds of Kher Keep for zero mana, you trigger Tangleroot to recoup your investment in green mana while simultaneously fueling The Great Henge's entry trigger to draw you a card. Before that draw resolves, activating Words of Wind replaces it by forcing everyone to bounce a permanent—allowing you to scoop up the very same Kobolds of Kher Keep you just cast so you can replay it indefinitely. Because The Great Henge also provides a massive mana discount and lifegain along the way, this cascade completely strips your opponents of their entire boards while you recast your free little kobold over and over again.
