Who said the Sun Dragons were unofficial cards, all we know is that nobody in the anime has heard about them before. Ergo, they are new cards.

And every character in the show could be ignorant fools who do not look up news for their card game, like everyone going head over heels when Shido used his new Death cards, never having seen or heard about them before.
