Standard Reaper fast expand which transitions into heavy Widow Mine drops/harass. Generally this build allows you to drop upwards to 4 widow mines in your opponents base around the 7:10 mark.
The main weakness of this build is the supreme lack of bio units available for defense. Which is why you might want to use a variant of this build which decreases the amount of mines and replaces them with some marine bio.
200 Supply means that the supply count isn't needed for the build step.
