How do you say tarot cards in spanish?

You say, "naipes de tarot," which means "cards of tarot." Another term that connotes 'cards' is "baraja de tarot", which means, "deck of tarot." "Jugar a barajas" means simply "to play cards." In Spanish, you don't put two nouns together and pretend that one modifies the other. It's usually really bad grammar.
