I personally like using self-capture to avoid protection forts/artifacts that my opponent might have. I once used a Disciples/Persians deck, because Persian Presidents can capture any of my disciples in the Fishing Boat. Since they would then go to Raider's Camp, I would get them back if my opponent should complete the rescue. However, since Persian Presidents usually get initiative, I could still use Haman's Plot and such to keep the Presidents alive for another turn. I also extended their usefulness by using Torment.
