According to their facebook page they have Landorus, Skyla, Keldeo, and Celebi. They might also do the Blastoise line soon.
"Several Boundaries Crossed cards are ready for play: Landorus EX, Skyla, Celebi EX, Keldeo EX. Might setup the Blastoise line when its available but other than that will probably wait for set list & all scans."
