I'm trying to put together something relatively simple, yet potent, for possible use in my first competitive tournament. It is my understanding that such gatherings can be extremely cut-throat, so I don't expect to come in first. But I don't want to hit rock bottom, either.

HQ
Lord, rez orb, warscythe
TROOP
10 Warriors

ELITE
10 Immortals

FAST
3 Destroyers

10 Scarab Swarms
HEAVY
Monolith
Monolith
This leaves a few points kicking around for more wargear. Haven't decided on that stuff yet, probably a phase shifter on someone. Maybe two phylacteries.
I realize this is not a lot of troops, but I have a hard time maneuvering warriors in such a way that they claim objectives. My basic plan is to surround them with higher toughness, more killy units, and escort them to the target by forcing things out of the way with monoliths and teleporting.
Additionally, I am thinking of dropping a monolith and the destroyer lord to accomodate a C'tan. The only thing stopping me from this currently is the fact that there will likely be a lot of tyrranid players, and I have heard that thier gaunts can get the ability to wound anything on a 4+. It would be pretty crummy to have my expensive death machine brought low by a horde of crappy little bugs.
All comments are appreciated!

Edit: Dropped the destroyer lord and made both immortal units x10 instead.
