First, you MAY spend one key to either move the Messenger to the other row OR discard the row the Messenger is on and refill it

After which, you have to buy a card in the row the Messenger is on, the cost is at the top left of the card. You may have ways to discount this cost, but never below 0. If you cannot buy a card, take any available but flip it face down and its features are no longer applicable, but you gain 6 coin and 2 Keys.

Regardless of whether the card you gained is faceup or facedown, place it into your grid orthogonally adjacent to an existing card whilst making sure not to go beyond the 3x3 boundaries.
