Paradox

This is a very strange card game. In the deck are 8 cards of this values: +1,+2,+3,+4,-2,-3. Shuffle the deck an everybody gets 4 cards. Turn over the deck and do what the card says. If it is a positive card you as many cards from this deck. If it is a negative card you discard that number to the discard pile and add the negative card. When the deck runs out turn over the discard pile and go on. When all card are in the players hands, all positive cards count negative and the negative cards count zero.
