I feel like you're another person who doesn't read the comments below before commenting your own.

Gargantua Dragon cards that don't belong in any world are not yet in the sim because they DON'T have a world to be in. Adding cards manually takes too much time as stated in A TON of comments right below us.

As for Lost World, well... there needs to be a few edits required to add it in the sim. Read the first 2 messages in this page so you can get an idea on how Otakon-san may add Lost World in the sim for the future.
