Glen VLots of sets have team pictures, but I can't think of any post-1913 set where every card has more than 4 players. The 1937 Kelloggs Pep Stamps have 4 stamps to a panel - that's the closest I can think of.
Not really that many sets where each card has 2 or more players - ones I can think of: ER Williams, T201, T202, E221 Bishop & Co., Sporting Life Composites, & Double Play.
