Veins of the Machine

Each player must exile 4 basic lands when this
card enters the battlefield.
All Artifacts other than this one gain Hexproof
and all Artifact Creatures gain Vigilance.
Metal-song 10: (If you control 10 or more
Artifacts, each Artifact you control turns into
an Artifact Creature with power and toughness
equal to it's mana cost and if this creature were
to die, return it to your hand after combat.)
