Hard to use cards

Last week, a customer came to our magic bar with a deck of cards of his own. He asked me to do some magic with these cards, and they turned out to be really really difficult to use. It is difficult even to tell the suits of the cards! The suit is written in the outer ring of the card, but the same suit can have a ring in different colors, and the same color can be used for different suits... In the end, I did some magic with those cards and he was happy enough.

マジックバーに来てくれたお客さんがマイ・トランプを持ってきて、これで何かやってと言い出した。大変使いにくいトランプだった、笑。何とか大丈夫だったけど。マーク分かりにくかったけど。回りに書いてあるが同じハートでピンク色も緑色もある…わけ分からない。
