I played a Swedish torunament with 38 players this weekend with a Thralls list.
This is the results of the tournament:

I came 15th place with Morphann&Namarti Corps.
2x Soulrenders
1x Soulscryer
1x Lotann
1x Aspect of the Storm
1x Allied Spellweaver
30x Thralls
30x Thralls
10x Reavers
10x Reavers
It is VERY difficult to play since it requires 12" wholly within from lotann & soulrenders, while 9" from the Aspect.
When the starts were aligned however I did plenty of wounds with everything and healed up 12-13 Thralls every battleshock.
Since Thralls healing has no limitations, I could ressurect them into combat with new units and deny them the charge on their turn. I could also heal up and conga line into other objectives.
All in all, I dont recommend it. Play eels or look at my cooler Aspect lists .
