Welcome to Librarium Online!
I'm kinda new to Warriors of Chaos, bought a small army 2 years ago but havent really played with it since. I bought:
24 (2x12) Chaos Warriors
5 Chaos Knights
Hero on Juggernaut (I dont think it'll be that usefull in a small army like this, but damn it looks so cool!)
sadly I dont have a sorcerer yet, I'm thinking of buying one when i've got time.
Anyway, I'm gonna have a few games with my friends this weekend, and I honestly dont know how to play Warriors of Chaos that well, or how to create a good army and use it well. I think I've only played like 2 games with it. I played more with my friends dwarven army.
I know Warhounds are used for "screening", to keep valuable units from harm until they get close enough, and thats about it. I dont have magic or ranged, so I should get my core (2 units of warriors?) in there fast and safe with warhounds, and try to flank with chaos knights, which is basicly a Hammer and Anvil tactic I heard, but that's about all.
We're playing 7th edition, my friends play Dark Elves and Vampire Counts (using shitloads of zombies and a giant I think). They might have some dwarves too but I'm not sure.
Anyway, help me not fail! I'll give you cookies in return! I definetly need a 1250 list, and maybe a 500 aswell, as a start battle (to keep it short and reintroduce everyone again).
Warriors REALLY struggle in 500pts. Our heroes are so hideously expensive we can get sod all on them. Points are really important and wasting them on upgrades is a bad way to go. Keep things simple and only take the most important things on your characters and units. We'll start with Core. You can probably grab both units of 12 Warriors into a 500pt game but you'll only just have enough points for a hero. So no Knights or Dogs. Or you could take one unit of Warriors and then squeeze in the Knights instead.
Luckily at 1250pts things get a little easier for us. We can fit in a hero or two, grab a decent amount of core troops and have enough points left over for Special and Rare choices. For 1250pts this is what I'd take with your models. Now I'm not sure what your models are equipped with so I'll just go with what ever.
Exalted. Tzeentch. Talisman of Endurance. Halberd. 
Sorcerer. Level 2, Spell Familiar.  Add a Mark if you want. If you're learning to use Magic Fire is very easy to start with as it's all blasty stuff.
12 Warriors, Halberds, Mark of Khorne, Standard, Musician. 
12 Warriors, shields, Mark of Tzeentch, Standard, Musician. 
5 Knights, Standard. 
2 units of 5 hounds. [XX]
this works out at just under 1000pts. So you'll need to go grab some more models or play 1000pt games. For the extra 250pts you could grab another unit of Knights/Warriors or grab a big unit of Marauders (like 30!) or something like a Giant/Hell Cannon or what ever takes your fancy.
Thanks for the response.
I dont have a wizard at the moment, but I can borrow one from a friend, and I'll buy one later I think. My warrior models are equiped with shields, but we have the rule that you can just state what they're equiped with at the start of the battle, so we dont need tons of models for different battles. As long as everyone honestly responds when asked what the units are equipped with, everything goes well this way. Its all friendly after all.
What do halberds do? I know they're a pretty cheap choice, but I dont know what effect it has.
You're saying I need more models for a 1250 point army. Do you think I've got a decent army when I buy both a sorcerer and a box of marauders? or should I go with even more warriors?
That's a good starting force. You've got all your bases covered. You'll have a bit of magic, some hard core troops, some speed with Knights and dogs and a choppy hero for a general
Halberds are two handed weapons (so you can have a shield with them to protect against shooting but you can't use it in combat) that confer +1 strength. However you still get to fight in initiative. Which is awesome. Although I've just realised you said you were playing 7th edition rules which changes a lot of what I've said in my previous post 'd'oh'
Marauders are all right but you'd need a few more. 16 is a bit too small for anything really. They're ok for hiding a sorcerer in to protect him from scouts and shooting but that's about it. If you want them to perform well you need a good sized block of them. 20+
