IN 3v3 I have done well with this
Boots/Blade/pot
Brute 1337
BWC/Ruined king (dmg stacks with his ult, passive stacks with his passive, lifsteal, dmg yes pls)
LW/or... Sanguine blade
Aegeis
Vandamns - only usefull late on zed, I rarely even end up getting this as the cost to get the hog and the upgrade really dont give you much. The vamp isnt needed after sangunine and botrk, you just run to jungle to lifesteal back to full health. Also RK gives you a good amount on active. The only thing this really does for you is alow you to gain a nice health booost from your ult.
Oh yeah boots get clown shoes if ahead for mobility or defence boots if behind (usually treads)
