Ok, so I went over to my friends house and I put them all together and we played a few games.
First things first. I actually decided while at the store that I would buy something shiny and special...I just couldn't resist the Defiler =D With adding the Icons, Champions, and a power fist to the squads i actually came to 740~ points. Which was a pleasant surprise.
I did however play a 500 point him as well using the above list. I loved being able to use two spells on one turn which was used to great effect against his 'Nids.
Pyro you are correct, the Terminator Armor really didn't make much of a difference. If he got into combat with his brood lord or his genestealers I was in Trouble all the same. (Though that Force Weapon was a nasty surprise for a carnifex (had killed all synapse prior)
I was bowled over in the first game, he got first turn and the dice gods weren't on my side very often.
The second game he used his Tau and it went much smoother for me. Aside from one slip up shooting the front armor of his devil ship in rapid fire and hitting 16 times, only to remember I couldn't hurt it >.<; but I crushed him.
We then played a Third and Fourth game; Against his Tyranids and his Tau respectively at 750 points.
The 'Nids had the tides turned on them. With luck on my side (also the defiler Cannon helped) I beat them, not by alot, but I did beat them. (Carnifex = Annoying as hell when only 3-4 of my guns can hurt it.)
The Tau I managed to demolish once again, even more so then the first time. But it was likely because of his terrible luck. (When a Heavy Bolter rolls a Six and gets a Glancing then Gets a second Six and destroys a piranha; This happened twice; It is pretty bad luck for him.)
So far my thoughts:
1) NEVER, EVER, EVER, EVER let 'nids even relativly close to you.
2) Terminator armor isn't that hard to punch through
3) The normal Chaos Marines are Durable little guys
Thanks for the ideas and thoughts. Glad to have my first games with my own Army. Was a Blast and plan to keep on Growing.
Any ideas for expanding? So far my thoughts include (but not limited to): Dakka Predator, Some Termies, a Daemon Prince.
