This build works by using the Hunter set buff with a high slash weapon build.

Why you would use a Sunika

Sunika are great for any high level mission where your getting any annoying highly destructive singular mob spawns. Examples being Nox, Ancients, Demolysts in Disruption, Eximus, etc. Any enemy that generally "gives you problems", the Kubrow is going to pin down over any normal enemy.

Though normally it is cited to be the best for Capture missions due to sometimes finding the target before you do.

The Kubrow gets up to +150% damage from the Hunter set paired with a [Hunter Adrenaline] on your warframe, alongside [Hunter Munitions] and [Hunter Track] on your primary.
Both [Hunter Munitions] and [Hunter Track] work nicely for a high status build.

Survivability
Link Health (base health)
Primed Pack Leader (or pack leader)
Hunter Recovery

Other mods
Primed Animal Instinct
60/60 Mods ([Venom Teeth] for Corpus & Grineer, [Shock Collar] for Robotic, [Flame Gland] for Infested or any high armor enemies, or [Frost Jaw]).
Link Armor for frame with a high modded armor, or Link Shields with something like [Hildryn] instead of Link Health.
[Primed Pack Leader] (or [Pack Leader]) is only useful for Melee focused builds, so switch it out if your using a primary or secondary focused build, for something else for Survivability such as the Link mods or [Metal Fiber].

Make sure you set up the abilities that proc' such as [Unleashed] and [Savagery] in the first slots on the left, because it will then proc' them most often.
