Tinfingers

Whenever a player casts an Artifact spell, that
player exiles it and reveals cards from the top of
their library until they reveal an Artifact card
with a mana value equal to or lower than the
mana value of the exiled card and puts that card
onto the battlefield. Afterwards, the exiled card
is shuffled into its owner's library.
