It seems Konami is trying to revive Blue-eyes decks, but according to some people there are still unfixed game bugs on some Blue-eyes cards like Blue-Eyes Solid Dragon.
Good question.
I did try Solid dragon's effect before and it doesn't always work. When your opponent activates a card's effect like Kiteroid or Gravekeeper's guard it doesn't prompt you to shuffle Solid dragon.
I guess Konami bugged Solid dragon on purpose so that you buy this new Blue-eyes instead.
