Kind of deck with sailor not leaving navy (5)
I believe the answer is:
tarot
'kind of deck' is the definition.
(I've seen this in another clue)
'sailor not leaving navy' is the wordplay.
'sailor' becomes 'tar' (tar can mean a sailor).
'leaving' suggests deleting specific letters.
'navy' becomes 'N' (common abbreviation eg in RN Royal Navy).
'not' with 'n' taken away is 'ot'.
'tar'+'ot'='TAROT'
'with' is the link.
(Other definitions for tarot that I've seen before include "Pack member" , "Sort of card" , "Special cards for fortune-telling" , "Arcana cards" , "Cards used for fortune telling" .)
