Will unified minds be legal for Worlds?
Yes, August 16th is the 3rd Friday of the month of the release of the set.
This is why I am
optimistic about Worlds, but also
impatient.
I want to know the full set of cards Worlds participants have to work with, right now!
But I'm also optimistic, because this set is huge, so anyone who practices for Worlds,
thinking they know what the card pool is going to be, may be receiving an unpleasant surprise, and show up to Worlds unprepared, having practiced on false assumptions for several weeks, as there will (hopefully) be a few cards in the set that are unexpected.
