Lord of the Pyrrhian Legions -- Whenever Anrakyr the Traveller attacks, you may cast an artifact spell from your hand or graveyard by paying life equal to its mana value rather than paying its mana cost.

Creatures you control are artifacts in addition to their other types. The same is true for creature spells you control and creature cards you own that aren't on the battlefield.

Whenever you cast an artifact spell, you lose 1 life and create a 2/2 black Necron Warrior artifact creature token.
