Gravestone
When scoring, if Gravestone is in your Yard, Gravestone is worth 1 VP.
When Gravestone is played onto a Pile in your Yard, choose any one card from the Store, put the chosen card onto the bottom of the Store Deck, and then restock the Store.
Gravestone’s play action (▶︎) is not optional: When Gravestone is played onto your Yard, you must put a card from the Store onto the bottom of its deck. Gotta bury something in that grave!
