6th edition Chaos Space Marine builds

Been grinding away at the new Chaos Codex. The first thing that springs to mind, which I didnt dismiss outright was the Chaos lords.

The new chaos lords have alot of options and you can really make some nasty buggers. These lords will molest most things, except one or two special characters, in melee. Should you meet those special characters .... gun them down.

So we wanna make our lords hardcore killers. We wanna make sure they survive. We wanna make sure they get to the enemy.

HQ choice:

Chaos Lord 175
- bike, mark of tzeentch, axe of blind fury, sigil of corruption, mutation, veteran of the long war
Chaos Lord 165
- bike, mark of tzeentch, powerfist, sigil of corruption, mutation, veteran of the long war

Bikes should be selfexplanatory. He is T5 which is pretty much eternal warrior for most practical purposes. You get to the opposition fast and you get 3+ coversave, which is redundant for the lords themselves but not their body guards which we will see in a bit.
The sigil and the mark of tzeentch combined gives a 3++ invul save.
The weapons are there to gank the enemy. Veteran of the long was is for hatred in melee with all marine armies.
The mutation is there for one of the lucky resulsts and for flavor. Just cant say no to a little mutation.

Fast Choice

2x 7 Chaos Bikes 354
- 2 meltaguns, veterans of the long war, (1 meltabomb)

These are the body guards for the lords. If you wanna do one or two is up to you. Two adds a bit more flexibility but also gets pretty expensive.
They are tough nuts to crack with T5 and 3+ armour or cover save.

I been in two minds about wether to give the lords Nurgle marks instead and also giving the bikers mark of nurgle. Its Nurgle or Tzeentch. Can´t mix them.

Troops

6x 5 CSM 770
- plasmagun, (2 combi-plasma)
- rhino

The followup troops that come in behind the bikers to control the midfield. The plasmaguns are there to deal with MSU marines.

Heavy

3x Forgefiend 525
These things are just awesome-sauce. The only shortcoming is AV12, otherwise 8 strenght 8 shots are gonna put dents in most things. And with the 5++ invul save and the ability to regen hull points. Whats there not to like.

The only thing i think this list has to worry about is flyer heavy lists. Otherwise the opposition is gonna get punched in the face and shot to bits and pieces.
