Suggestion Idea: They get no cards from their partner, turn ends immediatly. Maybe they do not get to take the next turn.
Specifics: Penalize the player that "elimantes" his teammate from the game.
Why it is needed: To keep overly aggressive players from penalizing their teammates. One partner gets cards and purposfully postions himself for his partner to get 5 cards and effectively get another turn in the same turn.
