Eyava, Prime Director

When Eyava enters the battlefield, all
Non-Creature Artifacts you control become Artifact Creatures with power and toughness equal to their converted mana cost. If those Artifacts had Equip, they lose Equip and gain Prosthesis. Their Prosthesis cost is equal to their Equip cost.
Whenever an opponent casts a Non-Artifact Creature spell, Eyava deals 3 damage to that player.
