Please read the annotations on the third picture, a lot of thought was put into this. I'm sure I saw a different post that did mention the slam storage tech/bug, but i did encounter it on my own before and only now, with this build, found a way to make it OP. Have fun with this.
Completely ignore your 3, get max 2 (to be able to proc tankbuster with it), then max 4, then max 1. The ammount of healing you get if you execute someone with your 1+lifestrike is INSANE. Im talking 1.5k to 2k insta heal depending on who you execute (The tankier the character you execute, the bigger the heal. I've seen 1024 healing from lifestrike alone).
This build plays like an assasin early-game of course, but it allows to get so far ahead if you get picks, being a bruiser/diver is actually doable in the late game, unlike stacking resist and playing like frontline tank (which I dont think is still viable on Silver)
Bloodtribute+Berserker are kinda psychotic, but you can toggle BT on and off (pre-fights) to get 10 berserker stacks without losing much hp and then keep it stacked in order to get insane ammounts of damage.
The build order is Melee lifesteal, CC, healbane, stalker,PB,Lifestrike,BRS,Tankbuster, HA,Berserker, BT.
Healbane is not as necessary ig, but the heal on kill is very nice, and stalker allows you to always proc it as well as BRS.
At max boons you are able to proc tankbuster with your tailwack as long as you keep the 4.8k spike and have picked ONE or more spirit power golden statue buff(s).
