I'm guessing the Dawnbringer, right? I assume no further responses since Oversoul's playing white and everyone else is tapped out or already stated no responses.
I'm guessing at the lands/mana you're tapping, but if you tap three lands, you have one extra in your mana pool from the Heartbeat.
So Dawnbringer is countered and it's still Oversoul's turn.
