Interesting card, seems like it would be pretty good in Volcanion; however, I don't think it will be very relevant in standard (assuming this set comes out after or right before Worlds) because cards like Kiawe are just so much better, not to mention that you can't immediately attach each of them from your hand to your Pokemon in one turn (unless Emboar gets a reprint). I just don't see this card being too amazing. I don't think Volcanion is going to gain relevancy in expanded again just because of this card.
Good concept, but overall, pretty mediocre (unless emboar gets reprinted OH boy)
