- 7 February 2025Once Ketramose has been declared as an attacker or blocker, it will continue to attack or block that combat even if the number of cards in exile falls below seven.
- 7 February 2025The ability that prevents Ketramose from attacking or blocking counts the total number of cards in exile, regardless of who owns them or how they were exiled.
