Boss's Chauffeur enters the battlefield with a number of +1/+1 counters on it equal to one plus the number of other creatures you control.
Alliance - Whenever another creature enters the battlefield under your control, put a +1/+1 counter on Boss's Chauffeur.
When Boss's Chauffeur dies, create a 1/1 green and white Citizen creature token for each +1/+1 counter on it.
