Your squad is good, but will probably struggle against mine quite a bit. Even if you hit, there's a huge chance of 50 coming back with Djem So, and Luke could wind up defensing the whole thing as well. Mace can Riposte, but will he want to risk the Djem So?

EDIT: You're right that Leia will be key here. I probably should have built in a bodyguard for her lol.

General squad notes:
Squad Summary
Sidious provides FR1 to Maul and Asajj, which boosts them considerably. Sidious and Ventress both have Cleave, which can be huge in this kind of play format. Sidious hits either for 120 Damage with attacks or 50 and Activation with Lightning 4. Maul can hit for 160 plus Riposte thanks to attacks, while Ventress hits for 120. Zayne's purpose is to try as hard as he can to get Cortosis Gauntlet off against the opponent's main attacker, while Salacious tries to distract enemy commanders.

Set-up
This squad has an advantage in that it is very flexible in set up, depending on how the opponent chooses to set up their squad.
Salacious should be placed next to either (1. As many commanders as possible, or (2. The opponent's most dangerous commander. Distraction for the first couple of activations could very well be killer.
Zayne needs to be put next to the opponent's main beat, so that he has at least a decent chance of getting off Cortosis Gauntlet and disabling that enemy character.
Sidious' and Ventress' placements don't matter a whole lot, though they should be placed where they can maximize usage of their Cleave. Next to low-HP pieces is a good idea.
Maul is best against a low-Defense, high-HP enemy. If none is available, put him where you think he would be best. Or, even, just place him wherever is left.

Play
This squad is very simple to play. Lightsaber Block with Zayne against dangerous enemies as much as you can, in the hope of giving them -20 Damage. Salacious doesn't do anything, but attacking with him wouldn't hurt. It is generally a good idea to have Ventress and Sidious target low-HP characters first, so they get off their extra attack(s) from Cleave, though don't go out of your way to achieve this. Sidious can also activate the opponent's stronger pieces with Lightning 4. Again, Maul is there just for Damage, and Teras Kasi helps a lot with survivability.
In the event that the opponent has a disruptive or distraction piece that is affecting Sidious, target that one first. It needs to be destroyed, utterly, and completely.

Please note that I will not be able to play my squad. I'll provide some suggestions here, however, on how to play it against my first opponent, adam0nd:

First Match-up notes:
Obviously Double Sorcery is extremely dangerous. I'm expecting that he'll use Revan to win Init., then use Marka and Bastila to activate as much of my squad as he can. There aren't any disruptive pieces to worry about, but Revan can be a major issue. Place Salacious Crumb adjacent to Ragnos (and Revan, if possible), so that he can't pull a double-Sorcery.

If he DOES NOT activate Bastila first:
(This includes if you go first.)
Try to take out Bastila with Sidious as soon as possible, so that she can't use Sorcery, and so that Sidious gets off his Cleave. She NEEDS to be killed in the first activation. Use Force Points to re-roll, if you have to.

Once Bastila is gone, concentrate all attacks on Revan -- both from Maul and Ventress. Eliminating adam0nd's initiative control is a major goal, and that Swap can be very dangerous.

If he DOES activate Bastila first:
Take out Revan and go from there. If that Initiative control isn't eliminated, the Double Sorcery next round will be almost unstoppable.
If Revan isn't killed in the first round, and Salacious is still alive, refer back to the starting conditions. If Salacious is dead and all of his squad is alive, then the game is probably pretty much over -- but still try to win, anyway.

can i still enter a team?

SignerJ, do you have someone you want to sit in for you? Any volunteers?

Haha. Even with IG-88's second attack, Dengar would have won if he hadn't rolled 1 in round 6.
