Tricks as Robin has victory last week in ... (9)
I believe the answer is:
hoodwinks
'tricks' is the definition.
(I've seen this in another clue)
'robin has victory last week in' is the wordplay.
'robin' becomes 'hood' (I've seen this in other clues).
'has victory last' becomes 'inks' (I can't explain this - if you can you should give a lot more credence to this answer).
'week' becomes 'w' (abbreviation).
'in' indicates putting letters inside.
'hood'+'inks'='hoodinks'
'hoodinks' going around 'w' is 'HOODWINKS'.
'as' acts as a link.
Can you help me to learn more?
(Other definitions for hoodwinks that I've seen before include "gulls" , "pulls a fast one" , "Bamboozles" .)
