I joined the project last year and It's a pleasure to work with so many good Artist XD (I was doing a Sakuya character card and "The world" spell card XD)
Here's the promotional video of the card game
Apparently there's 151 cards in total, including character card, spell card and event/battle field cards, and every single card was drawn in very detailed quality.
However I guess you still need to read Chinese in order to know how to play the game XD
This is the Taobao Link for people who would like to order the card set
The new Pokemon Artbook by Ad.nap should be coming out soon as well
