I really needed to know whether cards in the latest set that was just released: Fates Collide, would be legal to play at UK National Championships 14th-15th May.
Fates Collide will **NOT** be legal for the UK National Championships.
Sets are not legal until 3 weeks after the release date. The release date for Fates Collide in the UK is May 4th (today!!) which means it will not be legal until May 25th for tournament play.
