Well, maybe we can bring Malifishmertz too. Since we passed the double-Stewardship action (with flying colors) that frees us up to take a shot at moving the castle.
For Stewardship next turn I'd suggest Castle Doofhawk and either buying out Lee Industries or ACME Express Delivery.
And Diplomacy reaching out to both Shego and Khan.
Learning I'd suggest Researching the Galfed Ship, and since it's alien tech it won't trigger Jumba's opinion drop, and Dino Domestication or Adaptive Cape AI.
I suggest wait until we finished Express Delivery Action. It's reward said that we would get a Trait that would applies Bonus to certain Stewardship action and having an instantenous travel time would definitely helps moving the Castle with that 125 DC going on.
