...I'm not so sure how cunning it is, but Sokka seems to think its our best shot. He wants to lure Yuber out to a specific spot over the tunnels by having someone challenge him to a fight. Once Yuber's there, Toph will earthbend a hole under him, and there will be a cage in the tunnel with people waiting down there for Yuber. They'll rush Yuber, and chain him up, and that will be that.
