PoE Flicker Strike, Duelist, Shadow builds

First time building a build from absolute scratch, need some help reviewing some of my choices (tree nodes, uniques, etc) Don't pay attention to resist, most items have mid-low tier rolls. Take into account only accuracy, damage, crit chance and so on. Any advice is really appreciated!

PoB: So the idea is to go Trickster to make flicker free, and then to go MoM to take advantage of that defensively. I am doing this rather than Terminus Est Crit Flicker because I'm a hipster I guess? I've started every league since Breach with Oro's flicker, and I know it is quite solid for everything up to and including yellow maps, which is all I really need for a league starter anyway. Any suggestions for improving the build? Don't pay too much attention to the gear, I was mostly just playing around with the new "sort by dps"
