Actuall combo should be like this: E(when you are far from your target)>Q>W>Rewind>Q>W>E(to get away from enemies)>and if you rly need it to escape then R
For second build combo is E>Q>W>W>rewind>QWW here doesnt matter>E and to get away from enemies R

Just check that build and give me feedback about it.
I know that this guide isn't wrote good but just wanted to show you my build
