Artifact Creature — Wall

Defender (This creature can't attack.)
You have hexproof. (You can't be the target of spells or abilities your opponents control.)
Prevent all noncombat damage that would be dealt to other creatures you control.

Ikoria's crystals glow in the presence of monsters, making them valuable as both defensive fortifications and warning beacons.
