He didn't control the Marines bro... When stimmed marines can step back really fast, kill a few units in a second and then step back again and kill more units... What you don't want is the mutas on top of your marines while lings are still alive....
@draganpetev4677 This is a big part of it, but I think another big factor is that Hyun had +1 air vs +0 armor on the bio. But yeah ling muta is incredibly powerful, Soulkey does it all the time
Oh dude Saiyan says he "flew the mutas right in" but that was intentional and crucial because he used hold position and you can legit see all the muta attacking different marines and the +1 air just shreds everything Damn that's so sick
