It seems to me that there is going to be a major shift from big, bad, basics to bigger, kind of bad, evolutions. Ultra ball will likely fight for its position as a staple against the new timer ball. We'll see how the new format reacts to discarding cards in order to refresh hands. The Ilima card seems interesting - it's essentially a Birch affecting both players. It could be fun for casual play but I doubt it will see much competitive play if N doesn't rotate.
