I was in the mood to make a new list and I remembered the fun times I had with echo when the TIE Phantom came out, this time around I'm thinking:

Echo w/ VI+rebel captive+FCS

But that leaves the mod slot and I'm wondering if the 2 additional dice from ACD are actually worse than the evade token from stygium accelerators? Anyone crunched the numbers? Any good aces to run with Echo are also appreciated

The bonus of ACD isn't only the extra two dice, but also the decloak. That's how you keep Echo consistently confusing.
