I have mostly been playing Dreamer, even so I've yet to use Carver or the Bandersnatch, as I do not own them. I haven't felt a need to pick them up though as the crew feels very strong using mostly the units you listed, with the additions of Serena Bowman (she is the #1 most important addition in my view, always performing well), widow weaver (harder to use but also quite handy and fun) and teddy (does what you'd expect). Hinamatsu, Doppleganger and the Hooded Rider all seem useful as well, though I have mostly used them with Lucius to date. I'd say of Dreamer's keyword options, Insidious Madness, Stitched and Serena are hard to go wrong with, favoring more stitched in say reckoning, and more Madnesses for any really schemey pools. I am curious to know how important Carver or the Bandersnatch are though, as I like the models a fair bit and will end up getting them eventually...
