I've found that making them re-roll their greens in some way usually messes them up. And focus fire as always.
Also, most people seem to be running the mid-PS pilots, with MAYBE Vessery at PS8. So out-PS'ing them can also work. Making them use tokens they'd rather not to stay alive.
I faced 2 Vessery/Ryad/Omega Leader lists and a Vessery/Inquisitor/Palpmoblie list at my last tourney and I beat all 3. I had Dengar and Asajj, both with abilities to make the enemy re-roll greens (R4-B11 and Zuckuss) and it made them melt. I killed a focus/evade Vessery in one round of shooting due to Dengar's double tap and Asajj all focusing on him and making him re-roll.
Can you give us a full list? Sounds like a fun/interesting one
Sure thing. A bunch of people asked for it at the event as I went 5-1, with my loss being the final round. I was surprised I did as well as I did. But coming up against 3 lists in a row that hated my green dice shenanigans was pretty lucky.
Dengar: R4-B11, Lone Wolf, K4 Security Droid, Glitterstim, Punishing One
Asajj: Veteran Instincts, Zuckuss, Glitterstim x2, Gyroscopic Targeting
I called it Dengar's Mistress
