Favor of the Kami
One copy of this card, which is available in the Disciplines of the Void Clan pack.
The LCG business model is great if you want to own every card but it can get expensive to buy a 16$ pack when you're only interested in a few of the cards. So I give you the option, you can buy the entire pack or if you prefer you can buy individual cards instead. As the game gets older it'll get more relevant to be able to buy individual cards instead of 35 different packs to make one deck.
