See actor dart off for Wheel of Fortune, say (5,4)

I believe the answer is:

tarot card

I'm a little stuck... Click here to teach me more about this clue!

'for wheel of fortune say' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'see actor dart' is the wordplay.
'actor dart' anagrams to 'TAROT CARD'.
But, I am not sure how the anagram is indicated.

'off' acts as a link.

Can you help me to learn more?

(Other definitions for tarot card that I've seen before include "I forecast" , "fortune-teller in suit" , "One from fortune-telling pack" , "Empress?" .)

I've seen this clue in The Daily Express.
