Mycosynth Lattice + Collector Ouphe

Mycosynth Lattice

Collector Ouphe

How it works

1. Mycosynth Lattice turns all permanents into artifacts.
2. Activated abilities can not be activated due to Collector Ouphe.

By weaving Mycosynth Lattice into the battlefield, every single permanent you and your opponents control instantly becomes an artifact alongside its other types. This sweeping transformation turns lands, creatures, and enchantments alike into targets for Collector Ouphe, whose static ability shuts down all activated abilities of artifacts. Because lands are now artifacts, their mana abilities—which are classified as activated abilities—are completely disabled, locking your opponents out of generating mana or using crucial game pieces entirely.
