As Borgin and Burkes enters the battlefield, you may pay 2 life. If you don't,
it enters the battlefield tapped.
The cursed opal necklace that Harry saw in Borgin and Burkes in the summer before his second year at Hogwarts, is given to Katie Bell
by an unknown person to deliver to someone at Hogwarts.
