Magic Designer Publishes Part 9, Admitting 2 Sets Missed Their Vision

Part 9 of the weekly “Lessons Learned” series says The Lost Caverns of Ixalan changed more than almost any of the nearly 50 sets the designer has led or co-led, with its original underground-world vision failing to establish a workable identity.
The article says that failure stemmed from forcing a long-sought “color matters” theme into the set; feedback killed five color-specific Treasure-like tokens, craft shifted to card types, and a late move to Ixalan redirected space to explore and Dinosaurs.
Murders at Karlov Manor is presented as a different kind of miss: the murder-mystery concept produced mechanics such as investigate, disguise, Cases and collect evidence, but the genre supplied plot beats more than a strong environment.
The designer argues the set should have leaned harder into Ravnica, saying roughly a 30% file change could have improved it, and closes by framing both projects as examples of vision design going off course.
