Is there a technical hurdle here like a restricted API or something? I like to brew before a release given that the cards are already spoiled.

The full spoilers just barely was released and it does take a while for Sebi to import things. He does it all himself so things can run slow. I am sure it will be done before the weekend, but dont quote me.

Sebi generally adds sets when they show up on Gatherer, which is usually the Monday before the release.

Speaking of...it's up on Gatherer now, Sebi. There are braces in the url so I can't directly to the Aether Revolt cards.

Would love to see this soon! Dying to update some decks
