Ozzel with only 10 activations behind him is a bit of a waste of 11 points, IMO. An opposing squad with Dodonna or San Hill, or even an opposing Ozzel could match or beat your activations quite easily, especially at 200 points, and then you're going to be in trouble. Besides, I don't see you really needing to out-activate to guarantee the Oppurtunist. Once Zuckuss has pinned the enemy piece in place, it is only a matter of time until it must be activated, at which point you run up a swapper, switch in Vader, and obliterate the hapless target. I would drop Ozzel for more Brutes/Uggies and perhaps a Camaasi for Gambit stealing.

I'm also not such a big fan of Dengar. Final Shot is okay, but without Accurate or Sniper he's going to be wasting it on Mice or Evading Ugnaughts more often than not and, even if you do pull it off, he's pretty much defenceless unless you waste the swap on him instead of Vader. I don't know what I'd replace him with, though... Arica, perhaps? She's worked for me before in similar squads.
