Do I control cards in my Graveyard, Deck, and Hand? (Mtg)?

A card says target card I control gains X, can I select a card in my Graveyard, Hand, or Deck?Do I control cards in my Graveyard, Deck, and Hand? (Mtg)?
Cards you control are those on the battlefield, because only you can use their ability (in most cases) while it is on the battlefield, not your opponent. Your Graveyard, Hand, and Library are special zones that have cards you own, but don't control.Do I control cards in my Graveyard, Deck, and Hand? (Mtg)?
