Yeah it was astonishing that he had so few deaths for a game that is considered one of the hardest to do Nuzlockes in, and with a "no items in battle" restriction nonetheless. The most unfortunate death there in my opinion would have to be Caesar the Roselia who died such a cheap way, to Horn Drill from a Goldeen.
But then there was also Aquaducked the Golduck who came to the rescue against Giratina after it killed his two Flying-types. He started off so weak but managed to defy so many expectations.
