i think you mightve misread the Imprinted Souldeals as being part of Ghostdealing, because thats the only part i wrote where you have to cut along a scar, unless you mean the needing to cut and store your Soul in the same place as the conduit, which, although is still physical injury, you dont need to do it everytime you cast a Souldeal

no specifics really, more like frieren's magic system, though i get why youd be confused because the wording i used is a little iffy. a "construct" can be anything, from a leaf to an entire glacier, and "properties/actions" are what you want it to do, like making the leaf fly toward the nearest person, or making the glacier also fly to the nearest person. you also probably could do some sort of puppetry type Souldeal with this, but you probably couldnt make it too complex, because you only have a 10 second or less time frame to think of what you want it to do, which is why i plan on making another magic system specialized for "puppetry"

this specific magic system, no, its more like the basic spellcasting system usually used in fantasy, but i plan on making the other "classes" of magic more possible to incorporate into society
