Combo is in the video, only needs
1 Union Hangar and random lv4 (you wont even use it, it's just Bujinki Ahashima requirement). Similar combo can be achieved by using Unauthorize Reactivation too, thus raising the consistency. Union Driver is important here as union equip and Shooting Riser Dragon fodder, so we're running it as multiples. Skull Meister is used because it's a lv4 handtrap. 1 Nibiru because we can search it via Gallant granite if we already draw Adamancipator Researcher.
