My criticism will exclude King and nearly everyone of occult tendencies (8)
I believe the answer is:
mystical
'my criticism will exclude king and nearly everyone' is the definition.
I can't tell whether this defines the answer.
'occult tendencies' is the wordplay.
'occult' becomes 'mystic' (I've seen this in another clue).
'tendencies' becomes 'al' (I can't explain this - if you can you should believe this answer much more).
'mystic'+'al'='MYSTICAL'
'of' is the link.
Can you help me to learn more?
(Other definitions for mystical that I've seen before include "'Esoteric, spiritual (8)'" , "Sacredly obscure" , "Slimy act? (anag)" , "Having a spiritual significance" , "Inexplicable" .)
