I think so, they should be up at the same time together, and yes, they can also ship together
Is there any kind of window of time slightly more specific than "coming soon" for that link? A few days or weeks from now? After the holidays? I don't mean to pester, but saying that the cards will be available for a limited time but can't be ordered yet puts pressure on the customer to not miss the chance to use something they paid for (the access link) and having nebulous start and end times for that opportunity is a bit of unneeded stress.
Sadly we didn't have a concrete time for the cards. The vendor is still working on making the cards, as it is quite a lot. We originally wanted to have the cards ready by the time this pack launched (like the PokeWeen pack), but alas we didn't get that
But don't worry, the card will be available for a pretty while long after the sales of this pack conclude. So no need to rush. Expect a week or two I think until the vendor is ready with all the cards.
