Warhammer 40,000: Kill Team (HoR)/Tactics/Death Guard(8E)

Like their loyalist brethren, the Chaos Space Marines have a grand amount of customization available to them. Their basic troops are tough and they have a good list of guns available, and the access to the Daemons Opus and the newer books makes all their corners covered.

Your common keywords are Chaos, Heretic Astartes, <Legion>, and <Chaos Mark>

Rules

• Legion Trait: Your troops still have Inorexable Advance.
• Champions of Chaos: Similar to the loyalists, you can make models that share all of the leader's keywords into Core models or double the number you can take of certain Core models. This also includes the aligned ones, for better or worse.
• Localized Infection: Pretty much limits any unit-affecting rules to only focus on models
• Daemonic Ritual: Your leader can summon Nurgle daemons for free once per movement phase. Unlike the vanilla traitors, you can pretty much shit out Nurglings and Plaguebearers from the word go. Fortunately, these daemons don't count towards the rout check.

Armoury

• Covenant of Blood: Khorne leader only. You now have the ability to deny a power, which is perfectly necessary with your lack of psykery.
• Covenant of Excess: Slaanesh leader only. This adds an extra attack on the charge. If you intend to focus on melee, then you're going to like this.
• Covenant of Plague: Nurgle leader only. While double the price of the other covenants, this gives a lot more. See, your boss gets to deal a mortal wound on himself (Subject to being ignored if he gets Disgustingly Resilient) and for the rest of the turn, anyone within 3" takes a -1 to hit.
• Covenant of Change: Tzeentch leader only. You can cause perils if your deny test rolls a double 1 or double 6. In truth, it's a nice trick, but it's less vital than the others.
• Covenant of Tyranny: Unaligned leader only. You make anyone within the range of IP re-roll any 6s on a Ld check. Nice, because you'll need your troops where you want them.
• Bloodslicked Warplate: Khorne model without Terminator armor only. There's more than a few weapons with AP0, but if you know that the enemy floods the floor with them, take this for a re-roll against them.
• Pox-Encrusted Adamantium: Nurgle model without Terminator armor only. This suit's even heavier, granting +1T and granting a 6++ invuln, but your model now moves like it's always in difficult terrain. Better hope you're not going anywhere fast.
• Ectoplasmic Armour: Tzeentch model without Terminator armor only. This is evil, so EVIL. You know all those re-rolls those bosses give to their lackeys? Gone. All gone. And you just flipped them off. Just hope that the weapons aren't already enough to do you in.
• Diaphonous Battleplate: Slaanesh model without Terminator armor only. Flamers and other auto-hit weapons now need to re-roll the number of hits they deal and drop the highest, guaranteeing you a bit more protection form their kind.
• SPIKEY BITZ: By the dark gods, they return. Every fight phase gives you a chance to deal a mortal wound to one random schmuck within 1" of the model.
• Occuli Maledictum: Hidden models within 12" of the bearer are immediately exposed, making you a good foil for scouts and stealth suits.
• Haunted Adamantium: Good for more morale-busting, but not for sneaky. It bans hiding, but it makes anyone within 6" (or IP if the model has it) take -1 to Leadership.
• The Arch-Summoner's Staff: A force weapon custom-made to help summoners. This gives you the chance to re-roll a summoning roll, though any doubles you roll spell bad news.
• Ti'Lath's Boon: Tzeentch leader only. This is your single-use psyker-jacking power, and as such is worth the lulz you'll have when you steal a Grey Knight's hammerhand and toss it onto the possessed he's fighting.
• The Edges of Madness: Khorne leader only. You get a power sword/axe combo that grants an attack plus any more if the bearer charges and takes hits on the overwatch. While this is dandy for making a killing off a pack of overwatching Tau or Dark Angels, it does jack for survivability.
• The Death Toll: Nurgle leader only. You get a hand flamer that goes d6 hits with S3 AP-1 D1, but the real kicker is the penalty to WS just for being wounded. If you ever needed to sic your marines at someone and have a shot at winning, you throw this first to soften them up.
• The Killing Caress: Slaanesh leader only. The profile's pretty unimpressive, being only a CCW with 2 Damage, but you then notice that you'll never need to roll more than a 4+ to wound, which is pretty decent. You'll always attack first, so you can use this even if you're not running Emperor's Children. Actually, you should because running this with EC is kind of a waste for something you already have.
• Smoke Grenade: Same as the other Opuses, this thing gives you a zone of obstruction, protecting you from anything trying to aim across it.
• Screaming Engines: Bikes and jump packs only. In the event that you really need to make a charge, this lets you roll 3d6 on a charge, dropping the lowest.
• Hypercharger: Gives a bit of an exchange between BS and one gun's Strength, which might be handy if you know how to game your odds. Especially useful since you lack snipers.
• Bloodseeker Ammunition: Not compatible with auto-hitting guns. This will give you a little push in demolishing any sort of armor, but this only triggers on a 6 to wound with a gun.
• Willing Sacrifice: This model can take a mortal wound in order to help accomplish a ritual. Since you lack any heals on this, you're going to need this on multiple models or else seriously limit your use of this.
• Relic of Caliban: Fallen only. This forces any loyalist Dangels to direct all their fire at the bearer, but if they ever die as a result of this, you give over an extra VP. Make sure the guy has major protection if you use this, because you just picked DANTE MUST DIE MODE.
• Suspensors: Pretty useful if you plan to tote around heavy weapons, though the range won't be the same.
• Personal Teleporter: Cult of Destruction and Terminator only. This is your one means of compensating for the crappy movements of these models, though it's just as random as advancing without any of the fallbacks.
• Targeter: Lets your model re-roll 1s to hit if they stand still. It's cheaper and easier to grab than a familiar.
• Hungering Grimoire: Psyker only. Lets your sorcerer heal a wound if they kill an enemy with mind-bullets or swords, but not with pistols.
• Tome Malefic: Ruinous Invoker only. The ability to swap one prayer is pretty useful, but you should be sure that you want it switched, since you're only able to do this once.
• Daemonic Visage: Robs 1" from all charges against this model, which is pretty nice. Combine with the right terrain and you have someone unreachable.

Familiars

You have a rather decent list of familiars available to more than just psykers. Leaders can pick two different ones while anyone else just gets one.

• Reloader Familiar: The EVIL armourium cherub. This only re-rolls 1s to wound, but it won't go away after one use.
• Linkdevil Familiar: This might make retreating a bad idea for the enemy, as it lets you shoot once with a pistol or make one whack if they fall back.
• Combat Familiar: This one's a bit of a mixed sell, since it costs more if your model's stronger, but weaker guys shouldn't be fighting anyways. In any case, it's two free attacks at the user's strength AP0 D1.
• Spell Familiar: Psyker only. This allows you to re-roll a warp die, but you perils if the re-roll matches the original roll.
• Regeneration Familiar: Leader only. Normally the most expensive familiar, but this gives the power of regaining lost wounds...until you roll a 1 and get another mortal wound instead.

Philosophies

• Whim of the Gods: +1 TP for never using Tactical Re-roll.
• Mind Games: +2 TP, but only if you aren't the first to make a Tactical Action. Evens the field a little if you face loyalists that use the one philosophy that demands that they do this thing.
• For the Legion!: +2 TP for only using the <Legion> Tactical Action. With how many of your tactics involve pre-game shenanigans or single-use tricks, you'd be less likely to side with this.

Tactical Actions

• The Galaxy Burns (2 TP): Your <Legion> models all get one extra attack for the fight phase. Especially useful for melee-focused forces.
• Beseech the Dark Gods (2 TP): Your daemonic ritual now has a chance to summon multiple daemons. Quite nice if you plan on spamming them.
• Chaos Boon (1 TP): The Eye of the Gods returns. On any turn were your leader slays another leader or 3+ lesser models, you can roll for a Chaos Boon, though you must re-roll being a prince or gribbly.
• Escape Artist (1 TP): Fallen only. Remember that trick where Cypher can vanish without conferring any VP if he dies? You get that chance too.
• Murderous Descent (2 TP): Night Lords only. All flying models can re-roll their charge distances, but only if they arrived from reserves during this turn.
• Misdirection (1 TP): Alpha Legion only. You can re-deploy any two non-cultist models before the game begins. Add this to the ability to use this multiple times, and you'll have redeploy your whole team - if you can spare that many TP.
• Iron Bastion (1 TP): Iron Warriors only. Pick a single piece of terrain or block of 6"x6" mat with a model on it. You add +1 to any cover bonus this applies. Not very siege-like, but you have a big wall to protect your forces.
• Fury Unleased (2 TP): World Eaters only. Your leader gets +1 attack for each enemy within 1", but rolling a nat 1 to hit makes them hit a friendly model within 3" with the anger of Kharn.
• Dark Zealotry (3 TP): Word Bearers only. Your leader's IP doubles in range and all models within it auto-pass any Ld check, but you're barred from voluntarily routing. Pretty helpful for holding a line while calling up reinforcements.
• Traitors Ascendant (1 TP): Black Legion only. Your DZ is now expanded by 3". Enjoy your extra room.
• Unholy Perfection (3 TP): Emperor's Children only. Funny, they have the same pick-a-roll tactic as the Iron Hands.
• A Taste of Freedom (2 TP): Renegade Chapters only. Your models can re-roll all 1s for one phase. It's only got one use, so make sure this counts.

Unit Analysis

Your FOC is as follows

• 1 Leader
• 1-20 Core
• 0-3 Special

Leaders

• Blightlord Terminator Champion:
• Plague Champion:
• Plague Surgeon:
• Tallyman:
• Plaguecaster's Apprentice:
• Seeker of the Mantle:
• Cultist Champion: Let's face it: If you're taking him, it's not going to be to fight. He's absolutely shit at that, and he can't even take anything aside from trash weapons. He's got a risk of backfiring on rituals, he lacks any benefits from <legion> traits, and he can only use IP on other cultists. So why take him? Because you wanna load up on your other boys. Simple as that.
• Possessed: This is the guy you want to lead a possessed force. He makes 0-5 Possessed Core and has his extra mutations to bolster his lessers. If there's any issue, it's that fucking atrocious pricetag.

Core

• Chaos Cultist: A pathetic distraction. Their only options are for one out of ten of these fuckers. Otherwise, figure out what you want them to die doing and keep them staying there while your real soldiers do business.
• Plague Marine: The basic goon, these are standard marines that can grab chainswordss in place of bolters to give them a bonus attack. Every 1 in 5 can grab a good variety of guns from melta to plasma guns to missiles. One can also grab an icon, which can help with spreading their love across the board and ease the load from the cult troops.
• Poxwalkers:

Special

• Noxious Blightbringer:
• Journeyman Blightspawn:
• Biologus Putrifier:
• Deathshroud Terminator:
• Blightlord Terminator:
• Those Thingies: Expensive units, but using even one gives you a unit easily capable of tying up whatever comes across it. Throwing one at an enemy while escorting a Leader or other key unit can force the enemy to prioritize between firing at the thing as it charges them and use up their Overwatch or ignore it to fire the other guy and get charged anyways.
• Possessed: Deadly bastards, they are pretty good for their price and their random powers are useful in combat. However, they absolutely NEED to get into combat in order to be useful. Being Death Guard, they sadly lack the protection afforded by Disgustingly Resilient and thus will likely be passed up without any Apostles or Possession-Masters to help out.
