As a Master Summoner, your Familiars have not only become strong allies, but also resources that can be used to further enhance your own strength, that of your allies, or other Familiars.
By choosing an unsummoned Familiar Card, you can {Sacrifice} it, and gain a {Buff Card} instead based on the Familiar you've sacrificed. These {Buff Cards} can be used to enhance a target, yourself, an ally, or even another Familiar.
