Certain Marxist's caught in deal with case of loot (8,5)

I believe the answer is:

treasure chest

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

'case of loot' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?

'certain marxist's caught in deal' is the wordplay.
'certain' becomes 'sure' (synonyms).
'marxist's' becomes 'Che's' (Che Guevara the Marxist revolutionary).
'caught in' is an insertion indicator.
'deal' becomes 'treat' (I've seen this before).
'sure'+'ches'='sureches'
'sureches' put within 'treat' is 'TREASURE-CHEST'.

'with' acts as a link.

Can you help me to learn more?

(Other definitions for treasure chest that I've seen before include "Box containing gold etc" , "Repository of wealth" , "Box holding items of great value" , "Pirate cargo" , "Precious box" .)
