Trick from a card you'd rather not be dealt? (9,4)
I believe the answer is:
practical joke
'trick' is the definition.
(practical joke is a kind of trick)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for practical joke that I've seen before include "Trick played to discomfort someone" , "Prank designed to make a fool of its victim" , "Unkind prank" , "Jape - hoax" , "rag" .)
