Aether Storm + Encroaching Mycosynth + Damping Matrix

Aether Storm

Encroaching Mycosynth

Damping Matrix

How it works

1. Aether Storm prevents creature spells from being cast.
2. Because Damping Matrix prevents Aether Storm's activated ability from being activated, it cannot be destroyed due to its ability.

This lock leverages a brilliant rules interaction to completely shut down creature spells. **Encroaching Mycosynth** turns **Aether Storm** into an artifact in addition to its enchantment type, which crucially brings it under the watchful eye of **Damping Matrix**. Because **Damping Matrix** stops artifacts from activating their abilities unless they are mana abilities, players are barred from paying the 4 life required to destroy **Aether Storm**. With its safety valve permanently jammed, the static ability of **Aether Storm** stands unchallenged, locking everyone out of casting creature spells for the rest of the game.
