Arcane Beam

(Artificial spells in your graveyard can be targeted as though they were artifacts. If they would be returned to the battlefield, you cast them instead.)
Choose another artifact you control: Arcane Beam deals damage equal to that artifact's converted mana cost to target creature, then you gain that much life.
"House Ortell's crusade to eliminate non-sentient life cannot stop within its borders."
