Pick a card... how exactly? Do you mean like judges deciding who the winner is by holding up the portrait of the fighter they think should win? Because in Street Fighter III: 3rd Strike, they have a judgement system that takes place whenever the final round ends in a double KO; the judgement system uses three judges, and for your character to win, two out of the three judges must put up a portrait of your fighter; the last judge always seems to be random in deciding.
