  In a Two-Headed Giant game (or in another format using the shared team turns option), Mogg Flunkies can attack or block with a creature controlled by your teammate, even if no other creatures you control are attacking or blocking. In any other multiplayer variant, it ignores each other player's blocking creatures.
