Put target nonland permanent into your hand. You may spend mana as though it were mana of any color the next time you cast that card.
While the card is in your hand, if it would be shuffled into your library, itâ€™s instead shuffled into its ownerâ€™s library.
If you cast the card put into your hand this way, youâ€™ll control the permanent it becomes. However, Five-Finger Discount doesnâ€™t change who its owner is. If it dies, itâ€™s put into its ownerâ€™s graveyard. If itâ€™s returned to its ownerâ€™s hand, it will go to the hand of its actual owner, and so on.
