I think Agnok is a really interesting warlord. I'm not sure that losing all your command is the best approach though - I see his ability more as mitigating your command losses, and enabling you to always have a highly functioning economy through just the command phase. If you're winning some command of your own, you can shutdown your opponent's command game to a certain degree. Throw in the new arrangement at Elova IV and consumed by the kindred and you have a deck that can almost always have access to lots of resources.
The natural instinct here would be to try to jam elites or something, but I don't think I want to go that route. One of the most powerful effects on the Tau side of the alignment wheel is the card 'Doom', but many decks do not play it since it is too expensive, and only jam it when they can get a huge swing. Since we generate large amounts of resources, I think jamming 3 and having access to it very often isn't a bad idea. Sometimes it might just kill 1 or 2 elites in the HQ, but in that sense it lets us play some removal. Of course, sometimes it just wins you the game outright, and it cannot be backlashed . If they rely a lot on moving their units around, a calibration error could be waiting for them as well.
Anyways, heres the shell I came up with 'High economy Kroot':
Classical command units:
3x Recon Drone
3x Earth Caste Technician
1x Void Pirate
1x The Duke of Debris
3x Vash'ya Trailblazer
3x Kroot Hunter (assuming errata'd)
4x Agnok's Shadow
3x Trap Laying Hunter
3x Carnivore Pack (Kroot Hounds might be better ? Haven't played them a lot though. I like to sac these guys p1 to set up a doom)
3x Rampaging Knarloc
2x Gun Drones (3 in most Tau decks but the targets in this deck are just alright)
1x Inquisitor Caius Wroth (Great when you and your opp trade command. You generate a lot of resources so trimming hands can be wonderful. Doesn't die to doom)
2x Consumed by the Kindred (Great for resources but can be dead, I'm not sold on 3x)
2x Behind Enemy Lines
3x Guerilla Tactics
2x Calibration Error
3x Doom (!)
3x Arrangement at Elova IV
1x Vanguard Pack
2x Heavy Marker Drone
1x Evolutionary Adaptation
(49 Cards - 1 Free Slot. Could be 3rd gun drones, calibration error or heavy marker drone. Or second, Inquisitor Caius Wroth, a Kroot Hounds, or a Void Pirate/Duke of Debris)
Playing elites without backlash feels bad but the Knarlocs are so good that it feels silly not to jam them in, Especially since you can consume them if they look like they're about to bite the dust, and they can be 'tellyporta'd' using the new Guerilla Tactics. Besides, I feel like him and the Trap laying hunters are necessary to be a bit more fighty.
I need to test the build a lot against Kith, Chaos and Orks to get a good feel for the numbers, since I already have a free slot and I'm not entirely sure my utility slots have the correct numbers attached. I also need to see if the deck can actually fight - but the plan to just take tons of cards and resources and Dooming your opponents train seems robust enough.
Let me know what you think!
