Thanks guys, thesewee the toughts, that i needed so much! Some Inspiration, something like a brainstorm

I never played with a Warlock, and I want to try it -and surprise my opponents
I will participate in a contest -2750p, 3 games. The participants will be: 4 SM, 2 Orks, 2 IG SL, AMTL, Tyranids. So I'm thinking of a fully mechanized Ulthwé list, to support the Warlock. My main problem is the few activations (at 2750p it's only 7activations..)
2750 points
Ulthwé Craftworld (NetEA Army Compendium v20120208)
==================================================
AVATAR [25]
Spear of Khaine
GUARDIAN WARHOST (MOUNTED) [350]
4 Wave Serpents, 7 Guardians, Farseer
WARLOCK TITAN [850]
GUARDIAN WARHOST (MOUNTED) [450]
4 Wave Serpents, 7 Guardians, Seer Council
BLACK GUARDIAN WARHOST (MOUNTED) [400]
4 Wave Serpents, 6 Guardians, 2 Farseer
SWORDS OF VAUL TROUPE [250]
4 Falcon, Fire Storm
SWORDS OF VAUL TROUPE [250]
4 Falcon, Fire Storm
NIGHT SPINNER TROUPE [175]
3 Night Spinners
The guardians in Wave Serpents may survive long enough, because the Warlock is a true fire-magnet, or it will be free to move, because the opponents will be busy with the fast assault formations. My problem is the lack of flexibility -I like Ulthwé's popcorn units (4 Swooping Hawks, for 175p an easy artillery killer unit), the lack of my favorite eldar stuff ,the Webway, the lack of Vypers.. Even the Fireprism's are missing -because of the stupid +15p STILL in the 2014 Compedium -which is the only allowed army list in the tournament! So just pure force, not much of thiking, which is not really Eldar like -and crazy low activation number!
I'm not sure, it will work, just need some playtests..
