Icon needed for indestructible/prevent damage effect

Meto5000

Certain spells and abilities give the awkward keyword of "Prevent Damage" , FYI, there's already an established MtG keyword called Indestructible that is a lot less confusing. Currently, it's difficult to tell which creatures are currently indestructible since there is no indication, which can lead you to make mistakes in targetting with spells or effects that deal damage.
