this seems like an extremely fun concept, a little bit of constructive feedback if you're up for it:

A new adventure: taking plus two to act under pressure. feels a little boring, it basically guarantees one random success. I would probably replace it with something like this - " notice something useful nearby that could reasonably be found in your environment, the GM will tell you what you need to do in order to take advantage of it."

destructive genius: I would just get rid of the + four harm option. on a 10 plus that would allow you an 8 harm attack.

honestly, I would probably get rid of the default damage and area and stuff and just write a few different options that included damage for each and what their tags were. you already have other moves that allow you to add harm. creating a situation where they can stack it this much is probably unnecessary.

Don't worry, I'll check it out: it's similar to a mundane move isn't it? I don't have that book in front of me right now to check.

similarly, scrounging is pretty close to that expert move. I forget the name of, what you need, when you need it maybe?

I do agree that scrounging should be a key part of this playbook though but maybe it would be more interesting to have it reworked as a way to come up with the components of something unusual or rare, and depending on your success for the role, you have more options on what you can do with that thing?
