Crazy Family

There are 42 cards in a deck - 7 families each consisting of 6 members. Every player is dealt 7 cards, active player may ask any other player for a specific card, for example "mother of artist family". If the other player has it, the card gets handed to the active player. If the other player doesn't have the card, the active player takes one card from the deck and ends his turn. Next player is now the active player. There's one condition - active player has to have at least one card of the family he's asking for. Once a player has all 6 members of the family he can place it in front of him. Whoever has the most completed families at the end of the game wins.
