I'm trying to put together a list that makes it trollishly hard to kill the annoying Palob and so far I've got something like this:

It has a little bit of a dependency chain on Serissu because if she goes down Leeachos will only be able to Bodyguard Laetin. I could replace Opportunist on Palob with VI which causes the damage output of the squad to drop but removes the need to lock Palob into green moves.

I'm not sure if Laetin is a better choice than two Pirates but his ability works well with Serissu and Leechos if he's targeted. If I swapped Palob over to VI, I would think about shifting those points to give Laetin an HLC. I'm not sure what I'd do with the two points from Serissu's now useless Decoy.

I've got a feeling that, ultimately, any variation of this list may be too gimmicky to work against a wide variety of squads.
