Idea for a build: Suggestions?

I'm trying to figure out the fastest build for hell cows possible. I want to start with a few requirements.
1) Requires at least half of inventory available prior to runs. (This way I don't have to constantly stop runs to mule)
2) Requires minimal mana pot usage with AOE skills. (Redemption from Phoenix OR +mana on kill on a weapon)
3) minimal MF and resist is actually required, because I'm mainly farming cows for runes and gems.

Build idea:
Death Sentry Assassin
With this Assassin I can hit these requirements and complete hell cows quickly.

Requires
Weapon 1: Strong + skills claw
Weapon 2: Phoenix shield + redemption aura and -fire resist.
Helm: Griffon's Eye or Shako
Body Armor: Enigma
Belt: Arachnid Mesh?
Gloves: Magefist
Boots: Waterwalk
Ring 1: Soj / FCR stat ring
Ring 2: Soj
Amulet: +skill fcr assassin amulet OR Maras.

Merc:
Weapon: Infinity
Helm: Andy's
Armor: Eth bugged Fortitude
Gloves: Dracs, etc
Boots: Eth Goblin Toe / Eth Gore Rider
Ring: BK, Ravenfrost, etc
Amulet: Highlord's Wrath

Explanation: work in progress

Because Death Sentry provides Lightning as well as Fire damage, the damage is boosted by Infinity+Phoenix while providing Redemption aura utility. The Assassin will be able to teleport to Tristram to quickly get Wirt's leg with decent FCR. The ability to create traps will allow you to spend time picking up items instead of continuously attacking (saving time)

 

@colder is right. I think that the best cow king remains the CE necro, seasoned with summons or bone wall (for cow herding).
Javazon is another good option, but it takes more clicking than with the CE necro.
Trapsin, blizz sorc are close too, with lower killing speed though.

 

Thank you @colder. I will check out the link.

 

Cows? Hell cows? Only necro corpse explosion build ......
infinity merc, treachery, G Face.
your gear: enigma, Hoto, shako, SOJ, etc.
use Iron Golem (mana regen)

You need to press 3 buttons: teleport, amp damage, corpse explosion. Rinse and repeat.
