Avatar State

During your turn, Avatars you control have
indestructible, vigilance, and +1/+1 for every other Avatar on the battlefield under your control. However, if an Avatar you control would be destroyed, exile it instead.

"The Avatar State is a defense mechanism designed to empower you with the skills and knowledge of all the past avatars. The glow is the combination of all your past lives, focusing their energy through your body."
