Re: NeverMore Build
AC is indeed a filthy extension on him. You ain't never seen supports go down as fast as when SF shows up to the fight with an AC. Hell a CM with mass bracer starts hitting like a truck against -10 armor targets.
Generally either a BKB, dagger, or BoT rush is pretty standard. Other option is treads/phase + janngo extending into BKB, lothars, blink, or DoM.
Later on you are going to want some combo of tier 4 carry items. Aka satanic, butterfly, buriza/mkb, manta, AC, Skadi, BKB, and at some point swap for a BoT.
To say that SF has been played to death is an understatement. If you can't find 400+ comp replays in the last few years playing him i'd be surprised.
For great fun, try the classic weaver, Sf, venge, ES, generic semi-carry.
Weaver SF is a really fun double carry once SF gets an AC. You get some mind blowing negative armor on everything.
