Then you can prep/call in gank (if available). And, if you're lucky, he's not wielding a no-remove weapon and you can get a 1 rd strip off.
But the move is eyejab before he switches to swords THEN entwine. You do that, you likely kill him (especially with the mark firing sanc). That being said, good chance he evaded all of those commands and you're super borked by STSF :)
