Having to pick from the 'Scraps' and give them purpose, as well as to repurpose them plus revamp them was tiresome for Scarecrow to be doing, even as one of the Scraps that was given new life. The Black Realm was chock full of lifeless works from Tymon's history and in that, they were discombobulated and fully out of proportion. To even use any of the abysmal spatial rendering abilities that belonged to Scarecrow would do absolutely nothing, since each one had to be single-handedly given actual life from out of the essence of Tymon's own Free Will -- Tigen -- just the same as Scarecrow was.
