Have you upgraded your bots? Cause that really helps. Also be sure to check what abilities you have active and swap them out for more useful ones if needed. Also, some of that is just determination and luck. If you stick with it long enough, you will wind up winning the required number of times to advance. I don't mind losing, but I don't like losing so completely that it hurts. Like when I've lost three bots and my opponent still has four. I actually just foreit in those situations.
