Talk:A Episode 31: The Guardian of Order, Eden Hanazono!/@comment-4141313-20181222053221/@comment-5959367-20181222225755

Nothing is said that Eden (neither Kanesada and Neon) will join in Ranma's group for any reason. Even though their cards are in Violence Vanity, it doesn't confirm anything.

Golden Garga already has cards for 8 characters, added Yuuga's Magic Wold (and likely Katana World) cards too and all of them are characters close to Yuuga (ABC-cup participants, Aibou Academy students) who appeared early on in the series. Meanwhile Neon, Kanesada and Eden (also Rei, but we don't yet know anything about him) are rivals who appeared later on. Rivarly doesn't always mean they're evil, Yuuga is rivals with Subaru and Masato as well.

Now, if Violence Vanity only had cards of characters in Ranma's side, it would be cards of just 4 characters, and with Ranma having both Dragon World and Lost World decks, it would make just 5 different attributes. Compared to Golden Garga's 8-10 (?) attributes, it would be way too unbalanced booster set, so of course they have to put some other characters on Violence Vanity to keep the packs balanced and fair to people who buy them.

TLDR; Characters whose cards are in Violence Vanity aren't certainly going to join Ranma's group. They need to balance character's attributes in two sets, and some of those characters just happen to be more minor characters who appeared later on.

Also on side note, pretty sure Light's cover will be blown soon. His attribute has already been leaked a bit and it focuses strongly on opponent having cards under their flag. Lost World already has that part covered, so I'm pretty sure he'll be fighting against Ranma as it's easily good strategy to use against Lost World deck.
