Unavailable concepts versus renamed cards
These examples explain common old-build mismatches; this is not a complete history of every removed card.
| Name in an older guide | Status | What to do now |
|---|---|---|
| Call: Kyoko | Planned Chapter 4 concept; possibly scrapped | Do not search for a Kyoko boss unlock. |
| Call: Banished Knight | Scrapped summon concept | The actual NPC sells cards; fighting him does not grant this Call. |
| Call: Cruel King | Former name of Call: Blackrock King | Use the Blackrock King / Cruel King DX acquisition route. |
Choosing a replacement
Match the function you need before selecting an obtainable summon. Call: Blackrock King requires the optional throne-room fight; Call: Cassie requires Chapter 5 completion. Neither is a universal substitute available at the start of a new save.
