I've being experimenting with Ketsu Onyu, and am down to the following to versions.

Ketsu Onyu (52)

Shadow Caster title

Engine Upgrade

K4 Security Droid

Crack Shot

Inertial Dampeners

Glitterstim

OR

Ketsu Onyu (52)

Shadow Caster title

Countermeasures

K4 Security Droid

Expert Handling

Inertial Dampeners

Glitterstim

The first gives me a really high chance of double tractor beaming a victim for lower PS wingmates to savage; the second gives me a barrel roll (at the cost of a stress) to increase the chance of either a bump from aces or getting that arc on a victim to apply the tractor beam in the first place.

And having seen the success of Dengar with countermeasures/glitterstim, I have been kind of keen on it - although I will be the first to admit my ability to pick the correct time to pop it is not yet even approaching adequate.

Has anyone tried similar builds and what are you experiences?

Dengar Crew instead of K4, VI to go at PS9 and get some initiative boost by stopping at 98 or even 97 points.

I'd go Engine Upgrade over Countermeasures but it is also a nice defensive option

I tried Dengar crew on a previous build and found that so often I am rolling four reds and then only able too re-roll two at most was a veritable nuisance! Hence K4.

I like Engine, VI, K4 to help peg tractors on people. Ketsu can really surprised people, the long greens + Engine will ensure r1 shenanigans,
