Editing Warhammer 40,000/7th Edition Tactics/Renegades and Heretics (section)

===Battle Brothers===

*'''Chaos Space Marines''' - probably the most obvious one for both fluff and functionality. You get to combine the Helldrake AND Hydra flak tanks and DOMINATE the skies. As battle brothers your characters can join each others squads and/or benefit from each others abilities, so you can have an impressive number of psykers buffing each other up. Actually, any of the basic HQ units ''(but not Lords - see below)'' make good choices since Dark Apostles can make your massive renegade squads fearless & zealots and Warp Smiths can fix up your multitude of tanks that you'll probably have. 
**Unfortunately, this combination has a few glaring problems: namely, both detachments requiring themselves to be your ''PRIMARY'' detachment in order to gain the best goodies. So if you take Chaos Space Marines as allies, you lose out on being able to take Cult units as Troops choices, but if you take Renegades as the "allied" detachment you lose out on multiple units being unlocked through your Master of Renegades rule and you can only take a Demagogue Devotion if the model is your Warlord.
***NOT ANYMORE! Thanks to Traitor Legions, any allied CSM detachment which is described as one of the cult legions (Thousand Sons, Emperor's Children, Death Guard, or World Eaters) can take their respective Cult units as troops, circumventing the need for the primary detachment. So ally Plague and Noise Marines to your heart's content, little heretic. You may still not need a Lord over a Dark Apostle, but it really doesn't matter.
*'''Chaos Daemons:''' A good source for psykers, good melee units and deep strike deployment, particularly of objective holding troops (such as ubiquitous [[Plaguebearer]]s or the 2+ re-rollable cover save [[Pink Horrors]]). Soul grinders of Nurgle are now unspeakably awesome because they automatically have a 5+ cover save due to shrouded and have 4 HP with AV 13! Fantastic mobile cover, and they pack a punch, too! Troops are no longer obscene amounts of points in this codex, either, and heralds are fuckcheap HQ units; the mandatory units in an allied detachment can cost as little as 135 points, meaning you could take Soul Grinder support in lists as small as 1000 points and still be none the worse for wear. Meanwhile, bloodthirsters follow the flying monstrous creature rules and have WS 10 (10!). Lords of change are mastery level 2 psykers by default, level 3 with the upgrade (which you will always take) and can take either Tzeentchy witchfire powers or Divination powers. 
**Protip: Wanna make your Bloodletters or Daemonettes actually survive so they can reach combat? Run them straight towards the enemy every turn, then park a rhino/chimera in front of them and block all incoming fire! Then deliver your delicious, demonic payload right into those helpless loyalist corpse-fuckers' sphincter!
*'''Khorne Daemonkin:''' Permitted since Renegades are counted as "identical" to Chaos Space Marines with who they can ally with. This immediately solves many of the problems faced by taking Chaos Space Marine allies as the "Cult" units are already unlocked as Troops, but not that it mattered since you could take allied "Formations" instead of using the FOC. Also, the Blood for the Blood God rule means you can gain free daemon units quite reliably. Just be aware that '''only friendly units with the BftBG rule''' can actually contribute towards the Blood Tithe with their death, but since you can mix it up with melee & powerful ranged units you should have no problem accumulating those Tithe points from the blood of your enemies. It basically just means you have to be sparing with what allied units you can sacrifice.
**Ordnance Tyrant and lots of cultists. The enemy not giving you enough blood tithe points? Add Wyverns, then [[Grimdark|SACRIFICE YOUR OWN CULTISTS!]] BLOOD FOR THE BLOOD GOD!
**Since no one has mentioned this yet: Heralds. Of. Freaking. Khorne. Did you want a 55pt tax to make an unstoppable tarpit? Then you're in luck. 30 mutants + a Herald of Khorne is an insanely cheap blob of fearless fun. That big unit your opponent has without Hit and Run? Yeah... it's not going anywhere this game.
*'''Renegade Knight Household:''' Wassat? The renegades just jacked an Imperial Knight? Hell yes! The Renegade Knight adds an insane amount of dakka to an already heavy-firepower force. You can go either way between anti-infantry or anti-armor, just like your Renegades! Avenger Gatling Cannons tear through anything short of Terminators, while Land Raiders and Monoliths have a hard time against Thermal Cannons. Or just go fucking bonkers on walkers and monstrous creatures with a Reaper Chainsword. While a Renegade Knight adds a lot to any Chaos force, it seems Renegades and Heretics possibly have the most flexibility with it.
