Need help with a mechanic

Hey there. I was looking for someone that could coach me on how to perform the toyz technique. I have 400+ apm and as they say.... Knowledge is power. And I would like to learn, desperately so. There is very little information out there, and I don't know how to read korean or where to being looking for it over there. If someone wouldn't mind I would be very grateful, Im just someone looking to improve at this game that we love.
