Bad Piggies Drip Trap Drill

Only cards with Common or Mythic Rare rarity
can be cast or enter the battlefield, excluding
this card.
All players may cast artifacts from their library,
and as if they had flash. (To do this, look at
the top card of your library until you find an
artifact, which you may cast. If you don't cast
it, put it on the bottom of your library. Then,
shuffle your library.)
