I like it, but I think the same number points of OG vong or JH vong could destroy this squad. Their one threat would be luke and they could thud bug him. One vong squad not very competitive could probably kill luke pretty well. I submit that this squad could do such a feat, although it is pretty bad:

--Kill Luke--
78 Yuuzhan Vong Ossus Guardian x3
21 Yuuzhan Vong Shaper
19 Yomin Carr
11 Advance Agent, Officer
6 Advance Scout
6 Mouse Droid x2
9 Ugnaught Demolitionist x3
(150pts. 12 activations)

I do like your squad though. If you fight vong though, you are in trouble, even with djem so mastery.

Um, usually vong are played fairly close together, so runing in and out is going to provoke attacks of oppurtunity from the characters you are running by to attack your target. You are not goiing to run in and out in a single turn, so you will have to base one to kill it. The others all gang up on luke as soons as they are able. The OGs have Razorbug, so I if they have line of sight they have a 50% chance of killing some one on your team or damaging them.

If luke bases an OG and loses the next initiative, luke just lost eighty health from 1 OG. Without cunning, it's still 60 dmage with 9s or higher.

But this is a good squad nonetheless. You make up on low activations with dodonna and all the scrubs, but the vong who are immune to all of lukes force powers and can reduce the damage with a save of 6 are going to be a problem.

I might borrow your squad even sometime at my LGS b/c I think it'll be fun to play.

Don't use thud bugs, use razorbugs! or use FP 40....

You also need to understand that I can deny you the win by simply killing a few of your support pieces and then run away since Luke is 115 pts. With Master Speed and renewal 2 there is no way you can catch me (that's 24 movement). I will reiterate again how I can run in late round after you have activated everything and put 40dmg on any of your support pieces and then if I win inititiative or save the thud bug, kill off the said piece and run away and hide. Sure you can bunch up all of your pieces but that might just entice me to put 120 dmg on the piece or pieces that are adjacent. Or I might just run away allowing the Aoos and if you hit, Djem So Style Mastery for 60 dmg each hit. The fact that Luke cannot use lightsaber defense or reroll attacks or saves is not a huge deterent to this squad. Luke has an awsome attack matched with awsome speed. Vong can beat this squad with some really unlucky rolls on Lukes part. But the odds of facing this Vong squad matched with really unlucky rolls is so small that it doesn't make sense to give up on this squad because of it. Against any other squad Luke will just pound them into the dirt. I will test your squad against mine and we will see the results. Anything else is just pure conjecture.

I would like to try and come up with something that could defeat this squad easily, but when I think about it, I'm sure you can think of how Luke will beat whatever I think up. It's a great squad, especially if you're playing it the way you described.
Just one question. Could Count Dooku of Serrano pose a potential threat if he bases Luke? Of course, Luke could probably just take an attack of opportunity and escape Dooku, but one on one melee against Makashi might be a little tough.

Test games have already been played. Luke dies a fast and painful death to the CURRENT Vong squads that are top tier. So, this isn't even including the newer pieces we'll be getting in JA. It doesn't matter if Luke can run 12, hit something, then run away the next round. On average, he only does 10 damage to a Vong each time he hits them. Obviously, getting some Djem So saves in there helps (not sure if you can re-roll those saves against Vong...will have to check on that one). But here's typically how it works.

Luke runs in at the end of a round and hits a Vong JH twice, for likely only 20 damage because of Crab Armor. If Luke wins init, he hits that same Vong with Triple/Twin, putting at least 60 on him, and killing him.

Now, though, Luke is stuck in one place for the rest of that round. Two other Vong JHs come up and wail on Luke. They are a +13 with JH, and probably have Wicket backing them up, so they only need 6's to hit. They're also doing 30 damage, plus Poison, so odds being what they are, they probably put between 90-120 damage on Luke. That's just from 2 pieces. Now, the other Vong, hiding behind the JHs, namely the Shaper and Yomin Carr probably, throw Spit Poison attacks, for another 20 damage total (50/50 odds). Now, Luke probably got some Djem so attacks against the JHs, so he probably put 30-60 damage on each one. IF Luke is lucky enough to win init again, he can kill one, maybe both of the JHs with a Double/Twin. But now he's stuck sitting in the open once again, and then Yomin and the Shaper can spit poison him, again, probably doing 20 damage. So, let's count it up. Even if the odds are working against the Vong, Luke has probably taken 130 damage at this point (90 from JHs, 40 from two rounds of Spit Poison). If things are running statistically average, Luke is dead already. And losing just 1 of those inits changes the whole game, because then one of those JHs gets to activate and hit Luke twice more before Luke gets to activate.

It may not play out like that every single game, but it'll be pretty close to it. And this scenario here isn't even considering the possibilities of the JHs sitting a bit away and just tossing Spit Poison like crazy, forcing Luke to always move and only do Twin, instead of getting his massive Triple/Twin attacks. And if you choose to run away with Luke, well, you'll have to come back eventually, because the Vong will just camp in gambit then.

I've seen a couple test games, and sure, GMLS will work great against some builds, but he isn't the beast that everyone needs to fear, at least not at 150. At 200 you can build enough support with him to make him a Tier 1 piece, but I really don't think he'll attain that level at 150 right now.

I think this squad is one of the best GMLS at 150pts. Not sure it will own a Rebel Pushy Cannon though.

Oh yeah, forgot to mention that master speed doesn't stack. So you could use master speed to move twelve and attack, and then use move faster for another two since gmluke has motf 2 for 14 and attack. Or for 20 and not attack. His speed is quite amazing as long as he's willing to spend the force points, but its not as good as you originally thought.

But Djem-So is still an attack back at Dooku, so can't he still block it with Makashi? And if it were me playing Dooku against GMLS, I wouldn't even attempt Force lightning because it'd be a waste of needed Force points.

I have to give owaller credit for making a playable 150 squad with Grandmaster Luke in it, and also including init and door control too. Very difficult to do. However, I don't like the fact that you don't even have the pretense of a supporting attacker in this squad. The next most dangerous piece you have is Dodonna, with a pitiful +3/10. Once Luke activates, your entire round is over and he is free for the opponents to work over. Worse, if you get Luke stunned by the opponent, it is an absolutely lost round; you can do nothing until the next init. I have to applaud owaller for crating a 150 GMLS sqaud, but I just don't think it's competitive.
