3v3 GAC and Roster

[keen stratus]

Here is my account: https://swgoh.gg/p/583728597/

I know that my ship roster is a mess lol. It's an old account from 2017 that I just restarted in January.

I'm having trouble deciding which teams to put on defense and which teams to put on offense for 3v3 GAC. I have level 9 datacrons if you peek at that as well. I am in Carbonite so I only need 3 defensive teams
but I just got stuck on attack against a revan/malak team because I put my palp/SK team on defense instead of offense. I indeed got a hold, but I still lost.

More generally, if you want to just take a gander at roster and let me know what you think that'd be cool too. I buy every LSB and am so so close to getting GAS, Malak, and JKLS.
GAS: My endurance needs 40 more shards for 7*
JKLS: I need 7* Hound's tooth (55/100) which will give me 7* Millenium Falcon. My HODA is 6* but I saw there will be a LSB that includes him so I stopped farming him.
Malak: I am simply 4 gear pieces on Zaalbar away.
GL: I was originally going for JML, but now am close to SLKR and Rey as well.

TLDR: Need help. Old account. GAC teams.

you shouldnt have any problems with carbonite and 5 mil gp

i would just put your best teams on defense no one will beat it

ie: sk with level 9, plo with level 9, ns with level 9

do u need the team comps for these?
