Is Zekrom (Black & White BLW 47) still allowed in the new format, since Zekrom (Next Destinies NXD 50) still is.
This is what I found in the Play! Pokemon rulings:
"With the exception of basic Energy cards and previously printed cards that appear in Modifiedlegal sets, players may not use cards from Pokémon sets prior to Black & White. Players using previously printed cards that appear in Modified-legal sets must play those cards using the wording of the most recent printing of the card."
The way I read it, it still is, but I always thought this was only for trainer cards.
