Tangleroot + Words of Wind + Shield Sphere + Guardian Project

Tangleroot

Words of Wind

Shield Sphere

Guardian Project

How it works

1. Cast Shield Sphere by paying 0.
2. Tangleroot triggers, adding .
3. When Shield Sphere 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 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 cunning loop turns the free-casting artifact Shield Sphere into an engine of total board disruption. By leveraging Tangleroot's mana production whenever you cast a creature, you effortlessly fund the activation cost of Words of Wind. As Guardian Project watches your nontoken creatures enter the battlefield, its card-draw trigger is intercepted by Words of Wind's replacement effect, forcing you and your opponents to bounce permanents instead—instantly returning Shield Sphere to your hand to be recast repeatedly.
