Did you ever get an answer to this question @Brigby?
we have been asking this for weeks and weeks and there is still no definitive answer. one of many, many unanswered questions amongst them booster crafting, Ixalan, new story mode, c’mon guys this approach of no info then drop everything in one massive info dump/update is bullshit.
If answers are what you’re after, you’re best off adding your question to the developer Q&A thread. (And it’s a good question IMO)
Hi Everyone. I’ve already passed this question along to the rest of the team, but the card set restrictions affect a lot of different aspects, so we want to make sure we take them all into consideration first.
Once I have information available to communicate, I will be sure to let everyone know.
Before this pack rotates would be ideal, as it would have been for the last Kaladesh pack.
