Splendid Attire (first blind box). There are 3 unnumbered subsets from these boxes. 16 cards in each subset. I differentiate them by color of text on the back of the card (blue, green, red). These are gorgeous holographic thick (79 pt) cards with purple edges. Nice premium cards, pretty good quality.
This listing contains cards from just the 1 subset with the blue backs.
The Splendid attire 1 case contains a master set, so each of these are only 1 per case. These cases sold out quick on the Chinese market and are hard to find now.
