Special card for one to run round with (5)
I believe the answer is:
tarot
'special card' is the definition.
'tarot' can be an answer for 'card' (tarot cards are used to tell fortunes). I'm not sure about the 'special' bit.
'one to run round with' is the wordplay.
I cannot quite see how this works, but
'one' could be 'a' (a thing is one thing) and 'a' is found in the answer.
'run' could be 'trot' (trot is a kind of run) and 'trot' is located in the remaining letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'for' acts as a link.
Can you help me to learn more?
(Other definitions for tarot that I've seen before include "Pack of cards used in fortune-telling" , "Method of fortune-telling" , "Fortune-teller's pack of cards" , "one may have been taken from deck" , "Sort of card" .)
