For Unsanctioned , we needed a legendary blue creature with a red activated ability, so I said, 'Let's make it a clamfolk, so give me the best clam name you can give me.'

Overall, while a seven drop can be a tall order in EDH, this Octopus gives enough oomph to more than justify his inclusion, which is why he's found in 46% of Doctor Doom decks logged online
