basically if i kill all their buildings, and they still have their hero for some reason. I usually challenge them to a hero duel. This will take place on like an island or some sort, and no one runs off of it. Its heros only. And if they win, i usually quit the game, so they can have a win. So far the best luck i had was with a MK. The only thing i can kill with an MK is probably a Blademaster, but i can easily kill everyone else like a DH with no sweat. Its also cool, cuz at the start with both-metamorph, and then fight. its cool, u guys should do it.
