CS Game Terminology - Companion Card

From Unstable Games Wiki

Companion cards are found in the Companion deck and have unique effects that are continuously active, even during your enemies’ turns. Summon a face-up Companion from the Companion Portal when you transform into your Shadow Form by moving that Companion card to your Spell Book, then flip another Companion card face up from the top of the Companion deck to replace it. Once a Companion card is in your Spell Book, it cannot be removed.
