Good teams for Heroic Rancor (Preparing for our first run)

this is my team, as you can see i don't got them "well" geared, just rex cuz i use him on arena and ee cuz he is really easy to gear up, rex is the only one above 200 speed for arena at 224, ee is at 172, teebo at 172, dengar at 136 and qgj at 137, sometimes i got eaten at the end of p2 or mid p3, usually get to p4
