A player may attempt to conceal the names of any card in the history of Magic The Gathering in a proposal. Once all players have voted on the proposal, the proposing player may announce the concealed cards and receive one bonus point for each. If a player notices a concealed card, they may announce it ONLY at the same time that they cast their vote and receive one bonus point. Note it is entirely possible that a proposing player may name a card without realising it, these are also valid for points.
If a player successfully conceals the card 'cheatyface' (http://magiccards.info/uh/en/30.html
) into a proposal, they receive 10 bonus points. Note there are no bonus points for other players spotting this card.
