Deck Of Cards, Playing Cards, Cards
noun
トランプ comes from the English word "trump", as in "a trump card", but it means deck of cards or playing cards in Japanese. The Japanese meaning probably comes from card games played by English-speaking Westerners back in the day. Japanese people heard the word "trump" a lot, and assumed it meant a deck of cards.
