Quando Muralha de Ossos entrar no campo de batalha, use vigiar 1. (Olhe o card do topo de seu grimório. Você pode colocar aquele card em seu cemitério.)
When you surveil, you may put all the cards you look at back on top of your library, you may put all of those cards into your graveyard, or you may put some of those cards on top and the rest of them into your graveyard.
