Why isn't Gamorrean Guard used with Jabba?

He is. He just doesn't have uses elsewhere, so doesn't get priority for a lot of people.

1) Gam guard is only required at like r3 or something low, so you really have to invest more into a niche character to get use out of him. Jabba teams that are all r7/8/9 are worlds different than requirement level r5 teams.

2) Gam guard is useful in very niche metas where a second tank is useful, like the original GI counter with the empire TM cron. Almost all the rest of the time, Boba or Embo are better.

I think most people don’t use a double tank with Jabba. Boba Fett or Embo are typically the 5th instead

I run him with jabba, because my krrsantan goes with tarfful for a full wookies team

How does your Jabba with Gam perform in GAC,TW, etc?

I have fat roster and dont play 3v3, so i my jabba usually face weaker team most of the time.

I have him at R7 for the memes - I've put him on defense a few times, and gotten a few holds with him. But probably not because of him. I've reached out to a few opponents, and one claimed that Gam Guard made him lose out because he was taunting when Krrsantan was not, so he couldn't remove Booush. Another opponent said GamGaurd was annoying but not really a game changer for his counter.

So this past round of GAC I went back to using Embo as the 5th. IDK ... GamGaurd seems to fit REALLY well into the Hutt Cartel team, but I guess he just doesn't do that much.
