I'd like to ask if anyone knows if the option of choosing your family in the upcoming Streets of New Capenna prerelease event was left to the discretion of individual stores? I got told in the local store that the packs will be random for everyone and I can't make a reservation for a specific family. Is that how it's always been? Is there an official WotC mail I could direct this question to?
Usually you can always "trade" them with someone else before you all open them.
But in general there are not enough packs that everyone gets what they want.
A store can of course make a list of preference , but thats all up to the store if they want to do that (extra work, and some people might not be happy regardless).
Some stores might let people choose a color as long as there is a choice, all possible.
Simplest most convenient way however is to simply tell other people what you want and find someone willing to trade theirs, if thats not possible, well, thats how it is.
