On the cards as good advice? (3,4)
I believe the answer is:
get well
'on the cards as good advice?' is the definition.
I can't tell whether this defines the answer.
'on the cards as good' is the wordplay.
'on' is a charade indicator (letters next to each other).
'the cards as' becomes 'get' (I am not sure about this - if you are sure you should believe this answer much more).
'good' becomes 'well' (similar in meaning).
'get' put next to 'well' is 'GET WELL'.
Can you help me to learn more?
(Other definitions for get well that I've seen before include "Recover from illness" , "Recover one's health" .)
