Update: With the release of the Wild Blaze commercial, it is confirmed that this Pyroar is a promotional card, and not from the Wild Blaze expansion.
The April 2014 issue of CoroCoro Ichiban! released February 20 included a small preview of Pyroar from March's Wild Blaze expansion. This Pyroar is a Fire-type Stage 1 Pokémon that has already been alluded for the English Flashfire expansion. Wild Blaze comes out March 15, while Flashfire will be released May 7.
The second attack for Pyroar was unfortunately obstructed by some promotional text; however, it is known the attack does 120 damage.
