Hi I have been away from roll20 for several months but wondering how the cards work? For example I am porting a board game to Roll20 that uses cards and some of the cards may need to be hidden from the other players. Players can draw a card from the board game but the other players should not see it until the owner plays the card and then shows the others the effects of the card. Or it may be possible that the other player plays an effect that allows them to steal the card from the owner Thanks Dave
