Just hope you don't get grounded / come up against someone with alot of anti-air. Otherwise you lose on turn 1.
Well, not auto-lose per se, especially as most AA comes in the form of flyers themselves, who won't come on until T2 at earliest. Worst case you lose the very expensive mini who is probably your Warlord, and have full-scatter Deep Strikes on up to half a dozen units--hurtful, but not crippling. I figure you could increase the DP's survivability by giving him the Armor of Eternal Warring FNP, and honestly, hiding him behind some cover--that may well give your DS'ed units some cover saves or LoS blocking protection too, since they're not assaulting T1.
Ok I didn't make myself clear enough. Give a Chaos Lord The Axe of Ruin and then turn him into a Daemon Prince through Dark Apotheosis
It depends on how you interpret "removed as a casualty," since your opponent isn't scoring Slay the Warlord or anything, but I'd be inclined to say--and some frantic rules-searching on the day of a tourney a player brought the axe to yesterday--that RAW, you summon a Bloodthirster when the original bearer is removed from play, and again if the Daemon Prince is removed from play. Broken as hell and going to be FAQ'ed within a few days, if GW are at all on top of their crap, but... damn, better get some games in with the Bloodthirster Factory fast.
Some more observations from watching this player (who won the casual 8-player tourney with his list):
- FNP on a whole army is great. Blood cult creates fun number of Blood points, with the Slaughter Cult providing the universal FNP any time you summon a whole unit... (heard someone say only the Slaughter Cult gets the benefit of the lesser power used, which would make the ability a lot more manageable and specific, actually).
- Possessed have MoK and DoK, for Rage/Counterattack/Furious Charge, making them an actually pretty brutal unit... +2 A at S6 on the assault, plus their random bonus. Plus, well, with so many highly mobile high-threat value assault units moving up the board, they're just one of many, so your Possessed-Tax-in-a-Rhino isn't too high a threat... meaning they get to absolutely shred some face. According to how his matches played out, at least.
- Rhinos give up Blood Points! Never thought I'd be celebrating how much they resemble soggy cardboard, in terms of survivability...
- That summoned Bloodthirsters have to Swoop when they come in is a bit disappointing, and an argument in favor of summoning a Prince, but, say, summoning a Bloodthirster into the Axe-Lord who then spawns another Bloodthirster gives you a solid base of Anti-Air in a hurry. If you give up getting into ground combat, and are fine with them swooping until you need to land on an objective, 2 Bloodthirsters choosing to Vector Strike then Lash means they get 2D3+2 almost auto-hits at S6 AP2 on an enemy flyer or FMC. That will ruin a Flyrant's day in a hurry, provided you can line up the Vector Strikes for your first movement phase with the fellows...
- Consider allied Daemons with the Axe-Lord, since the summoned BT can take Invulns, so Grimoire is a solid plus. Using Blood Tithe points for FNP also gives the summoned Axe-BT another chance to save his D3 wounds taken per turn, provided you can rustle up the 3 BT per turn... that's a unit killed, a unit lost, and bringing the Blood Host? Manageable.
