There's nothing stopping you from apping a Servant from canon, the gacha is merely here as a suggestion. If you decide you hate our Servants, feel free to grab something from canon! Just uhhh, don't grab Gilgamesh. This is a benign Singularity according to Chaldea radars, there's no reason to bring in the big guns. Unless your Noble Phantasm is a big gun.
