My 2000 point list is alot different from his.
Avatar
3 wraithlords ( at first I had them with just brightlances, but I think the BL/ML combo works well now that I think about it.)
2 units of jetbikes with warlocks
1 farseer on jet bike either with warlocks on bikes and singing spears or on his own.
2 units of shining spears
2 10 man guardian squads or if the farseer is on his own, 2 20 man squads with scatter lasers.
Its got fast elements that can tie up enemy lascannon squads while the wraithlords and avatar march forward. It can be fearless.
I've seen a friend run a Nilla Kids list with 2-3 genestealer broods, 3 Fexes, 2 Hive Tyrants and 2 gaunt hordes and 2 zoanthropes, and he's done well in tournaments. Plus its a fun army for him, and I've always enjoyed playing him.
The wraithlords and avatar are a bit more durable then the Fexes, but have better weapons, and fewer wounds. The jet bikes are faster then the gaunts, and the shining spears are just as deadly, but fewer in number. But also more durable.
The guardians can use their firepower against hordes.....sure its BS 3 but its alot of shots.
I also have a list without the guardians, but with infiltrating scorpions.....but they are totally dependant on the mission.
