Filling up 50 points for Kromac

[Saekyn]

I'm going to try to get some games going tonight with some acquaintances at my shop, and I'd like to try out Kromac at 50. The thing is, I've got about 35 points or so for him and then I totally draw a blank on what else to take.

Kromac +4
WW Stalker -10
Pureblood -9
Gorax -4

Max Bloodtrackers -8
Nuala -2
LotF -4

What else can I take with him that makes for a competitive list? It should be noted, I'm already proxying the Bloodtrackers, and I own no other Tharn units.

kromac wants another stalker and lotf and stalkers wants a argus for 360 view
and skinwalkers for arm 20 models
always have shifting stones for any caster
maybe a worldwyried for some anti magic
gallows crove otherwise you will/should never use rift with kromac which is a shame cause its a good spell
his beast from domination works well
these arnt all auto includes but they all work well with him so mix and match
