Build based on ur items.
You can start with cheap items.
Like a low eth lacerator and a low eth warshrike.
Enigma ideally, but there are forti/duress/treachery if ur on super eco.
Guilaume is cheap either ias jool or cham if combi with wisp.
A 20fcr/3 soc helm is also strong but more exspensive.
Loh is cheap, early levels death sash + gloves are Nice.
Strings belt or arach
Gore boots, or war travs if want more mf.
Dual leech fcr ring
Raven or wisp
Cta phaseblade + hoto scourge
This thing can either be pure throw(which can use cheaper bo stuff) or mix of throw + singer with frenzy boosted throwing.
Ideally merc can be either Fana merc or insight merc.
This is kinda super eco one.
I made one early d2r just for fun. It can do hell, but its not quick. But at least u can mf with it.
The idea is jump on packs with spirit phaseblade and hoto war cry.
Quickly frenzy a few times to obtain Max attack speed(not needed with Fana merc). Then throw to amp enemies and then swap back and sing them to death xD its quite an active playstyle lol xD
Here is a example, far from optimal but cheap:

The most common build is:
Guilaume
Enigma
10fcr/dual leech adds ring
Raven
Hl
Loh / arach
Gores
Dual Grief Pb
Hoto + spirit or hoto + hoto.
Other viable wepon choices for frenzy is:
Grief Pb + azure
Or
Grief Pb + lawbringer
Merc for those is typical eth reapers might merc, meanwhile lawbringer merc can be pride might merc.
Azure and lawbringer is good for high undead density terror zones
