PoE Melee Splash 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!

Hello, i've been thinking about build based on Caustic Cloud spread by dying zombies but I'm not experienced with summoner builds. Its base damage is really huge so it's really easy to achieve huge dps, it lasts 4 sec btw Most of my problems are mechanics. My current plan is to detonate zombies with Coruscating Elixir(Umbilicus Immortalis to apply flasks, Maligaro Lens for 1.2k life heal per zombie) or eventually summoning over max(yes it works) but I don't think it's enough. Zombies are meant to die so they are rather low defence, I can't get any special spectres because Flask would kill

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"
