Unkillable Thrawn-led conquest team

If you drop your .gg than people would have an easier time helping. 

Anyone that prevents TM gains like Hux, JMK. High damage like JKL with a fast jedi, Grevious with his droids. Someone with daze like Dash, Taron, or Darth Revan with Malak.

Ad Rad with Rogue 1 can also do it, but that depends on your gear levels.

I just beat one of these with a Darth Revan lead, Sith Empire team.   Rogue 1, Tuskens, GAS 501st are likely to do the job.  I remember it, because I tried to do my 3 pirates feat on it and got TMed out of existence, just like you.

However, if you're struggling with speed in early sector 2.......I think you might be in trouble.

https://swgoh.gg/p/316424213/characters/ - I'm only on normal difficulty, so I don't have most of those characters. I've used a r7 FO team with hux and his zeta applied, and I can't seem to get any sort of meaningful hits.

https://swgoh.gg/p/316424213/characters/ is my gg, I don't have most of those characters. I'm on normal conquest, and even when I use my fastest character, Bossk (285), I can't get anywhere near even taking a turn.

You can't get it done with CLS, Chewies and Han?   Try 3po or Cpt Rex as the 5th.

After about 50 attempts and crazy RNG I was able to do it. Can't explain how but I'm glad to get past it. Sorry for whining.

First Order (without the GL or fangy Rey) aren't a good Conquest team.  Similarly, neither are BH (apart from against Night Sisters).  Both teams have very poor TM control.  As Conquest speeds are silly fast, you're in trouble with these 2 teams.

However, the CLS, Han,  Chewies, 3po is an exceptionally good Conquest team.
