Tangleroot + Words of Wind + The Great Henge + Shield Sphere

Tangleroot

Words of Wind

The Great Henge

Shield Sphere

How it works

1. Cast Shield Sphere by paying 0.
2. Tangleroot triggers, adding .
3. When Shield Sphere 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 Shield Sphere 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 turns the zero-mana cost of Shield Sphere into a devastating one-sided bounce engine. By using Tangleroot to recoup your mana investment every time a creature is cast, you can repeatedly pay into Words of Wind to replace the card draw from The Great Henge's creature-entry trigger. Instead of drawing cards, each iteration forces your opponents to return a permanent to their hand while bouncing Shield Sphere right back to yours so you can recast it for free.
