How to land a Daemon bomb in 6th

Having read the latest codex daemons book several times, something has struck me.  How exactly do you land your daemon models from deep striking.

Now I know this is by no means something you have to do in 6th, as daemons are capable of deploying normally like everyone else.  However you are likely to want to get your daemonettes and bloodletters to the enemy unscathed as much as possible, so you want a unit capable of planting an Icon.

Having looked at the various options, it seems there are three main candidates fulfilling the basic criteria of being fast and capable of bringing an Icon.  Lets take a look at them.

Blood crushers

How the mighty have fallen.  This used to be the premier assault unit in the daemon book, until the errata took its teeth and the new codex kicked it while it was down.  From a strictly combat perspective this unit is not great.  However, we are looking at it from the perspective of shoving an icon down the enemies throat as quickly as possible.

First notice, the unit is now cavalry, not infantry.  This improves its movement considerably, allowing it to move fairly rapidly towards the enemy 12+d6 inches on turn one.  It is still toughness 4 with 3 wounds and has the standard daemon invunerable save.  No sign of the power armour of yester year.  Three models and a banner will set you back around 150 points if you get a champion with an etherblade.  You might as well.
Not a great choice, but they will allow other khorne units to deep strike without scattering.

Plague Drones

I have to admit, when I first read the unit, I couldn't see past using them as a Tau Battlesuit style jump forwards, shoot two grenades a pop then retreat type unit.  However, the role of deep strike delivery actually suits it very well.  Toughness 5, three wounds, shrouded and an invulnerable save all contribute to being the toughest of the three units.  They pay a premium on their Icon, but you will want this.  Chances are you also want a champion with an ether blade as before, to give the unit some teeth.

On turn one this unit can move a considerable distance. 12+shooting+2d6.  The only real downside is that you don't really want to drop Plaguebeare units off close to the enemy, and those you might drop, like Beasts and Nurglings should probably already be deployed to attract fire away from your delivery units.  Like above, this unit is around 150 points and is considerably faster, tougher and move maneuverable than Blood crushers, but nowhere near as capable of combat.   It is therefore likely your units will scatter still, even with the Icon being held by them.

Seekers

The cheapest of the bunch.  For the low cost of 70 points, you get a very rapid moving, very low toughness icon delivery system.  To make this fair though, I will compare roughly 150 points of these against the other two.  So you can get 11 of these, plus an Icon for just under 150 points.  As these have rending, and are not especially tough, there is no point in buying a champion or an etherblade.  You get 11 wounds at toughness 3 and the standard save. So by far the easiest to kill, even with more wounds.  Each wound also removes a model, reducing its combat effectiveness.

On the plus side, they move like lightning due to being slaanesh daemons.  Move 12+6+d6 on turn 1 is outstanding.  They also work well with Daemonettes, Fiends and Chariots all of which are not very resilient and want to arrive unscathed.  You also have the option of taking two units of five, both with Icons for a mere 140 points.  The only reason I can think of not to do this, is that it eats into your fast attack slots, and fast attack for Daemons are vastly improved, and probably better than Elites and indeed Heavy Support now.

Tzeench

For some reason, Tzeench gets no units that can move fast and carry an Icon.  Neither Flamers or Screamers have the option.  Which is a shame really.  On the plus side, Pink horrors want to stay far and away from the enemy.

Conclusion

The three options are fairly competitive, in that none of them is substantially better than the rest.  Bloodcrushers are the slowest, fairly dangerous in combat, but lightly armoured.  Plague Drones are the toughest, and most flexible, but also are expensive, poor in combat and only have short range shooting. Seekers are the fastest and weakest, but slaanesh has the largest amount of low toughness assault troops.
