Tangleroot + Words of Wind + Kobolds of Kher Keep + Soul of the Harvest

Tangleroot

Words of Wind

Kobolds of Kher Keep

Soul of the Harvest

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, 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 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 cunning loop leverages the absolute economy of a zero-mana creature to systematically strip your opponents of their entire board state. By using the green mana generated by Tangleroot whenever you cast Kobolds of Kher Keep, you can easily pay the activation cost required by Words of Wind. As Soul of the Harvest triggers upon the Kobolds' entry, you replace your card draw with a bounce effect that safely returns the Kobolds to your hand while forcing each opponent to bounce a permanent of their own. Repeating this process endlessly lets you recast the free creature over and over, completely overwhelming the battlefield until every single opponent's permanent has been returned to their hand.
