I play him with Bloodrazor > BotRK, then 2 tank items based on team comp (typically go Visage for heal synergy and then an armor item dependent on who they got) and then the game is usually over by then. 6th item is whatever I may need. Frozen Mallet if they keep running away, QSS if they keep CC-ing me, etc.
I tried ghost at first. It does add to your R range since it increases MS but the difference seemed minimal, and the startup time after the nerf means you really have to be far away to get use out of it. And it doesn't help you much in getting out of a bad engage. Flash can help clinch an ult if they are a little too far away or it can get you out of a tough spot.
