I'm a Sombra main too but I tend to use translocator aggressively. what I do is throw it up in the air and hack them from above and me and my team melt them. or throw it up in the air and go invisible to run away.
NOTE: This Sombra only works if your team is good, go for jedijerboa's advice if they are not.
or you can also mix jedijerboa's advice and mine.
