Generally, no Marauder armies do not work. It's like playing with a whole army of swordsmen without the benefit of cannons, detachments, or shooting. Crimson will be able to help you a little more than me.
2250 Chaos Marauder Army
Characters
Exalted Champion
-Chaos Armor
-Chariot
-Shield
-Flail
-Trollhide Armor
-Gaze of the Gods
-274
Chaos lord, not exalted champion. LD9 is too vital to winning. Armor of damnation, gaze of the gods, and then the sword of might or the rending blade. Also needs a horse.
Aspiring Champion
-Chaos Armor
-Chaos Steed
-Battle Standard Bearer
-Banner of the Gods
-246
Nothing wrong here, though I might go with a cheaper banner.
Bray Shaman (cult leader)
-Level 2
-Staff of Darkoth
-Chaos Armor
-145
Drop the staff of darkoth, you don't have any herds worth using it on.
Chaos Sorcerer
-Level 2
-Chaos Armor
-Chaos Steed
-Power Familiar
-186
Take a bray shaman. Better in almost everyway and half the price.
Character Total: 851
Too many points. I would take khorne and drop the two wizards completely. Save a ton and still get plenty of DD.
Core
23 Marauders (sorcerer here)
-Full Command
-Light Armor
-Shields
-Flails
-209
23 Marauders (bsb here)
-Full Command
-Light Armor
-Shields
-186
5 Marauder Horse
-Music
-Flails
-81
5 Marauder Horse
-Music
-Flails
-81
5 Chaos Hounds
-30
5 Chaos Hounds
-30
Core Total: 617
Okay here, but I would use a unit of CW with halberds. Chosen. And some chaos knights.
Special
19 Bestigor (cultists, bray shaman here)
-Full Command
-258
Junk, bestigor are not really worth while. Take Chaos warriors or better yet, a herd of beastmen for cover.
4 Minotaurs
-Great Weapons
-184
Marauder Chariot (tuskgor chariot)
-85
9 Furies
-135
Nothing wrong with the rest of this.
Rare
Chaos Spawn
-60
Chaos Spawn
-60
Rare Total: 120
Take giants, not spawn.
This army is poor, but it isn't your fault. The mortals list without beast support and chaos knights is not a very good list. Wait until Novemeber before you buy any models. The new book should make things a bit better.
