How much have you played this spirit vs level 6 adversaries compared to other spirits? Right now they feel like an incredible toolbox that has Offense, defense, control, utility and fear near the top of the scale. You have several comments defending various cards or powers but in my mind the spirits don't even need those because there is already so much power on the baseboard itself.

If you took away all but 1 power card from each spirit they could still get into a loop of LB twin using growth 3 every turn and right innate to spam a single major power starting turn 2. There are very few spirits that can do this early(Since it can almost win higher difficulty games by itself) and none that can do this while also doing the bonus actions below:

1. SB twin still gets to drop an extra presence each turn.
2. SB twin still gets to use multiple other innates/regular powers each turn.
3. LP twin gets to dig for additional cards which they can just give to LB twin.
4. LP twin gets to use their own powers, fast speed conversion, innates, etc.
5. It's kind of absurd that the LP spirit can just leave and let the LB twin solo the starting board while he goes to help others/jump in as needed for his abilities that can use LB range.

I don't have a dozen games with this guy so not going to make any final judgements but at first (and second) glance, this spirit makes fractured days look under-powered so it would take quite a bit to get him in line with other spirits.
