Blastoise & Piplup GX Shining Synergy CSM2aC Chinese (simplified) 156/150

The Tag Team Collection was released alongside the Team GX Starter Deck in Indonesia.  It is the first exclusive set for Indonesia and contains cards from the last three Japanese sets of the Sun and Moon series.  Since the Pokemon Company had just recently started making cards in Indonesian this set is sort of a catch-up to get the Indonesian market on the same timeline as the other Asian markets.  Note that that only the the GX, Trainer Rares, and Secret cards have any rarity symbols in this set.  To read more about the Tag Team Collection visit Bulbapedia.
