Beat "All In" in Brutal

I finally beat the last level in Starcraft II "All In" in brutal. I was having trouble despite watching youtube on how others did that, but theirs seems easier because the waves seems to contain less numbers.

So basically I used the mind control device (but I did make a big mistake, I put the devices in front of the island where the artifact is instead of put it at the rear, puting them more at risk), and at the last moments I moved all my units to the center. After that, I kind of just waited and win because there are so much going on I can't do much.
