  Although Mogg Flunkies can't attack alone, other attacking creatures don't have to attack the same player or planeswalker. For example, Mogg Flunkies could attack an opponent and another creature could attack a planeswalker that opponent controls. Similarly, other blocking creatures don't have to block the same creature that Mogg Flunkies blocks.
