I have just started a month ago and I would appreciate any advice concerning which army I should use.

Well first of all in your fist army grapple is 15 points if I'm not mistaken. From what you've said I'm guessing you're working on a limmited collection so they aren't bad. I think I like the second one best though. Raptis' special ability has good synergy with the SA card. It is also better rounded with some okay support. It just looks like it will do better than a two mech only army (with the exception of the Shamash that is). That's just my opinion anyways. Good luck at the tourney.

Now I'm just a scrub but what about

Black Rose 253
malvina Hazen 46
Liao Arrow Iv Art Tank 47
liao anat 23
banson fa shi x2 46
banson shock troopers x2 32

447

of course I've just started so don't listen to me

That seems ok but I like to have my artillery in pairs so they can alternate fire. But other than that it seems pretty good. I will consider it.

so what did you end up playing?
