I got to try this list out yesterday and I am very surprised at how well it works. I was horribly concerned about fury management as well but is seemed to work out just fine the turns I ran them hot where the last two turns of the game and Lylyth was still able to reave enough fury from one to have it fully operational and the other frenzied against the Satyxis. Which was fine Lylyth was finally able to get a clear shot on denny I punked her in the face for 15 damage boxes and used blood lure so the Angilus could charge for free.
My raptors didn't do a whole lot but they got mistakenly positioned very poorly on the board and spent much of the game wheeling to get into firing range. The twin carniveans did exactly what I wanted them to, they soaked up all the aggression from my opponent and wow can they take a beating and keep coming.
The angilus is incredible for assassination runs, with lylyths feat and pouring it full of fury it can kill any warcaster/warlock in one run provided the warlock doesn't have fury to ditch the damage onto a warbeast.
I am very tempted to get either a forsaken to manage fury or a shepered not sure which yet as they both are amazing but have very particular uses. However, those shreders always earn back they points or more than their points. Perfect example the game I played was against pDenny and each shredder ate a bone jack.
Unfortunately the carniveans didn't do a ton of damage but they definitely work as a wall of flesh they tied up a nightmare a slayer and a whole unit of satyixs raiders for 3 turns and never died. Then again this has alot to do with Denny's feat it always seems against her once I get into position she rushes in pops her feat and I am the on who gets charged or my movement is diminished enough that I cannot even make it into melee and I am the one that gets charged the following turn. Her feat is just brutal.
