4 decks/packs of (playing) cards 撲克牌是 playing cards，亦即這牌是拿來玩的。 如果受了撲克這個詞的影響而說成 poker cards 就好像是在說這牌只能拿來玩 poker 而已。 Poker 就是梭哈，賭片裡常在玩的那種。 參考鏈結： 撲克牌：http://en.wikipedia.org/wiki/Deck_of_cards 撲克：http://en.wikipedia.org/wiki/Poker_(game) ==================================================== The following part is for native English speakers to see if my answer is appropriate. The measure word for playing cards is "deck" or "pack". So the translation for your question would be "4 decks/packs of (playing) cards". And please don't say "poker cards" even though that's how it's said in Mandarin. By "poker cards", it's like saying the cards can only be used to play poker only. Poker is only one of the card games.
