Title says it all. Looking to play him in a skirmish; was wondering if he was good or what to partner him with.

It's common to pair an AT-ST or Weiss with an elite Officer. Having only 1 attack can make these massive and expensive figures difficult to use well. The more it can kill with it's awesome attack the better. Therefore, the more it gets to attack the better.

That being said, it adds another 5 points to the cost of the AT-ST.

Personally I prefer the regular AT-ST to Weiss. His ability is not great as (like above) he wants to be attacking as much as possible.
His attack is more flexible but technically a bit weaker and the lack of a built in reroll does hurt him.
You do get the extra blast but it's also harder to trigger unless you swap red dice for yellows or greens with hurt his single target damage. So again, flexible but more expensive (and less range too).

His command card used to be an interesting addition, but now with the scoring and reinforcements changes it's probably even harder to justify than it was before.

I've had a lot of success with the regular AT-ST but that was a while ago, before the last few releases and before eStormtroopers were brought back in line.
It's certainly still an imposing figure and can be challenging to fight against especially if you've never faced one before. I think Vehicles probably need some new command cards to bring them back in line.

Perhaps his blast 3 is more significant in the newer tournament maps which have more enclosed spaces and tight corridors.

I've had a list with a reg ATST I've wanted to use for some time

Sorin, Advanced Comms

Officer

Elite Officer (more shooting)

Troopers to capture objectives

and every healing card and extra attack card I can get a hold of. Basically a one man army with the aTST

I haven't had a try with it yet, I chickened out at the last tournament and the way the jediknights running around with their Pierce 3 is I'd be more hesitant now.

That list looks quite fun. The Heavy Armor command card and Zillo Technique can both help you against the piercing Jedi.

I agree with Inquisitorsz, I generally prefer the regular ATST over Weiss. Weiss' reinforcement card is interesting in that it can bring back any trooper as long as the deployment card still has figures on the board and then is shuffled back into your deck, which is useful with Heavies or Jet troopers. The new rule update, scoring by figures, makes reinforcement an interesting choice now as when you bring some one back they can cause more harm to your opponent, but may give your opponent more points if you aren't careful.

He has shown up quite a few times since the release of the game in local tournaments, unfortunately it is much less often than it was at the start, but here are some lists I saw in the past that included him.

(Just after release, we saw him a lot before the following wave)

Weiss

E. Stormtrooper x2

Imperial officer X3 or regular Stormtroopers

---------------------

Weiss

E. Stormtrooper

rStormtrooper

E. Officer

Officer x2

(Just after Hoth)

Weiss
Sorin
E. Officer x2

Officer x2

Targeting computer

Rule by fear

(This list can be nasty with Zillo and/or Unshakeable)

(Around Bantha Release, when people were terrified of it)
Weiss

Atst

E. Officer x2

---------------------

Weiss

E. Officer
Temp Alliance
Bantha x2

I figure a list after the Jabba update would have Jet troopers, Stormtroopers, Heavy Troopers, Sorin, E.Officers, Probe Droids, Hks, Zillo, Rule by fear, and/or targeting computer. He probably pairs best with Jet troopers as their Trooper/Vehicle trait matches with him well. Maybe something along the lines of:

Weiss

E. Jet Troopers x2

E. Officer x2
---------------------
Weiss
E. Jet Troopers x 2

Sorin

Zillo

Rule by fear(or targeting comp or advanced comms)
---------------------
Weiss

E. Jet troopers x2

Jet Troopers

E Officer

Zillo


Edits: Spelling and completed a thought

I'm almost done painting my AT-ST and my Weiss, so I sorta wanna make a list with them too...

While not super effective, I've had a TON of fun with: Darth Vader, General Weiss, eOfficer, Zillo.

Use the eOfficer and Weiss to move Vader across the board much faster than your opponent anticipates, and wreak havoc with Brutality while sitting on a terminal or objective with Weiss. No, it won't win tournments, but it's super fun to play.

The beauty round:

On the Coruscant Landfill map, my opponent had initiative and set up in the indoors portion, leaving me out in the sand. Pass, pass, pass, pass. eOfficer moves Vader down towards red terminal. Then Weiss moves Vader to red terminal. Vader only one left to go. Vader uses Force Rush and Urgency to move 8 to put him dead in the middle of opponent's HKs. Brutality. Kill two HKs. End of Round, Receive Init. Vader goes first, Move, Brutality. kill Vinto, kill an HK.. .... he didn't have enough figures after that to burn Vader down.

That won't happen all the time, you won't draw Urgency and Force Rush in your opening hand all the time. Plus, anything with Pierce 3 (say.... Jedi Luke?) or those HKs with their forcing reroll is going to burn those double black defenders down. But still... it's fun to watch your opponent's face get all, "Whut" when you plunk down Vader and Weiss.

Heh, Weiss vs Rancor. "A TITAN AGAINST A TITAN!!"

TL:DR: Fun, but probably won't win many tournaments.
