Nobody talked about the Doppelganger
Basically it's a great model for all neverborn crew, because it could be what you want on the table.
With pandora, it gives you another WP test (manipulative), but I tend to use it for copying misery loves company with an action 0 and score some schemes (distract/deliver a message, plant explosive...). As you can make some interact actions in engagement, you also deny it to your opponent. And it gives you the right to cheat initiative which is great when you're playing with a crew based on activation control.
For the dreamer, I'll play my first game tomorrow to a tournament, so I can't tell you a lot for now. Strats & schemes are hidden and I choose to put it in my two list as a scheme runner. Coppelius is great too for that job but I could summon it, contrary to the Doppel'.
