In Ultimate Edition 2, the six Pathway lands originally printed inZendikar Risingare feature art showcasing the Plane of Kaldheim, and the four Pathway lands coming inKaldheim feature art showcasing the Plane of Zendikar instead.
This means across all printings of these cards, you'll be able to nab complete cycles set on either Plane—or both!
Like the firstSecret Lair: Ultimate Edition, Ultimate Edition 2 will arrive in a beautiful commemorative box that can be used for display. Due to issues surrounding procurement during the global pandemic, some of the boxes will be black and some will be dark gray. (There is no difference between the two other than color.)
