Creatures you control get +3/+3 and gain trample until end of turn. (Each of those creatures can deal excess combat damage to the player or planeswalker it's attacking.)
"You want to know your enemy? Look at your feet while you trample him." —Tahngarth of the Weatherlight

Overrun affects only creatures you control at the time it resolves. It won't affect creatures that come under your control later in the turn.
