Gravity Blaster

Select 1 Machine-Type monster on your field. Return 1 card from your hand to the Deck, and equip 1 "Gravity Blaster" from your Deck or Graveyard to that monster. If you select "Number 9: Dyson Sphere," you can also use this Skill without sending a card from your hand to the Deck. This Skill can only be used once per Duel.
