So, I'm always looking to bring something new to the table. Something people haven't seen before. I'm thinking:

Secret Society of Super Villains

Build total 600pts

What I have:

AA054 Despero 88/ Cont Plan 12
JL024 Chronos 77/ Alias 3
CR052 Psycho-Pirate 70
OR050 Mirror Master 58/ Auto Regen 12
OR091 Vandal Savage 133
AA103 Henchman 40/ AP 10
AA103 Henchman 40/ AP 10
AA005 Floronic Man 47

Though I am still in need of two Henchmen. I could lose the Pirate & two AP to add two more Floronic Men.

I do need a big hitter, Darkseid Exp from Icons comes to mind.

Other figures I can use are:

Crisis
027 Trickster and Pied Piper
Justice League
026 Captain Boomerang
Origin
090 Gentleman Ghost
Collateral Damage
037 Captain Cold
085 Felix Faust
Legacy
061 Blockbuster
062 Blockbuster
Unleashed
Killer Frost
Ultrahumanite
Cosmic Justice
Poison Ivy

Any suggestions?

I cant add much to this except dont forget about the feat card The Society for those with the IL TA. It may be helpful and its free

Prerequisites: Injustice League team ability

All friendly characters with the Injustice League team symbol have the following team ability instead of the Injustice League team ability:

When a character attempts to Outwit a power possessed by a member of this team, roll one six-sided die. On a result of 1-3, Outwit cannot be used by that character on this team member that turn.

I did remember that, but I wanted to try running without it so I could capitalize in the regular IL TA. It's such a great TA with the inexpensive pieces. Especially if those pieces have Flurry.

Are you using some sort of action cap? With only 8 figures,and two Leadership figures, you should have no problems using pretty much everyone with 6 actions, even if you do take CT into account.
Also, remember that wildcards cannot copy ATAs, so Mirror Master and the Henchmen will have access to the regular Injustice League TA.
I may have to steal this team later on BTW. I recently pulled a Psycho-Pirate, so I have been thinking about how to use him.

I was actually looking to use all the attacks at one time during the same action. That way my Opponent couldn't switch between JSA to Mystics to say Bat Ally between attacks. But I may just end up using the ATA after all if the regular one doesn't work on this team. Steal away, just let me know how it worked out.

Oh yeah, Auto Regen should be on Vandal Savage.

Definitely Contingency Plan. With that Leadership, it is a must. Especially against a certain figure that uses a phone booth and then Defend....you know what I mean. Make sure those attacks stick.
