I have a deck of tarot cards, which I bought for cos in the early stage (ller should know that it was used in Nozomi Tojo, and it took about a month to buy it.

First of all, tarot cards don't need any opening ceremony.

Secondly, if the tarot card is wrinkled, straighten it. You should take good care of it at ordinary times and cherish it as a friend.

Third, if you want to change a deck of tarot cards, just find an old tarot card box and put it away. It won't have any influence, and it doesn't need any ceremony.

Tarot cards are a tool for divination, and there are no monsters, just like astronomical mirrors used in astrology, so don't have too much burden, treat tarot cards correctly, and don't be misled by other people's superstitions.
