SE Secret Rare Archfiend Heiress X DARK Level 3 [ FiendEffect ] ATK 1000 DEF 0 If this card is sent to the GY by card effect, or by being destroyed by battle: You can add 1 "Archfiend" card from your Deck to your hand, except "Archfiend Heiress"
We can let our opponent attack and then use Gideon's Sacrifice like a weird Fog, not only preventing all of the damage we'd have taken but also passing it along to Stuffy Doll to throw at our opponent
Pair this with the fact that it's also excellent in EDH, and, as I said, you've got all the playability in the world
While I think the background pair is the stronger overall, and its what Id go with if building the deck from scratch, a general lack of token support and a need to justify all the horrors leads me to think Captain N'ghathrod deserves its spot at the helm
