The detailed listing is already available in Goodsmile, one of the popular stores which you can get anime goods. Moekana set includes 50 cards, 46 of which are hiragana, 3 character cards and 1 explanation card. Though it may sound simple, Dany explained to his post that there are some uses of the Moekana cards which makes it more intuitive. I'm not familiar on what kind of games he is talking about but he specified Concentration, Shiritori, House of Cards and Karuta.
I've been amused with the artworks and it would be a great medium that you can look up to when you're doing nothing during the day. If you're fond of reading magazines or just want to appreciate lovable illustrations then there's no way you will regret buying Moekana cards. If you guys are curious who are the cute chibis in the cards Dany explained that they are Mirai Suenaga, Haruka Suenaga and Kanata Hoshikawa. According to Goodsmile the cards will be available April this year.
