Master Artificer

Artifacts you cast cost {3} less to cast.
If you cast an artifact without paying its mana
cost this turn, scry 1, if you scry an artifact card
you may put it into your hand.
Whenever you cast an artifact from your hand,
create a 1/1 colorless Myr artifact creature token
with "{t} Sacrifice this creature: Add one mana of
any color to your mana pool, use this mana only
to cast artifact spells."
