I mean, while summoning magic is not a thing you could just make a magic that focuses on just making constructs like using ink to draw creatures or be able to summon puppets like how Sword Magic in the manga allowed the mage to summon a sword from their grimoire. 

Edit: If I remember correctly though, the specific swords had to be absorbed into the grimoire so maybe that wouldn't actually work unless the magic itself was puppeteering and then had a puppet made for later?
