Gambler seen on top of tavern, he may be the finest yet (6,4,4)

I think it could be either:

Which length description are you looking for?:

6,4,4

10*

better than ever

'the finest yet' is the definition.

'gambler seen on top of tavern he may be' is the wordplay.
'gambler' becomes 'better' (better is a kind of gambler**).
'seen' means one lot of letters go next to another.
'on top of' is a charade indicator (letters next to each other).
'may be' indicates an anagram.
'tavern' after 'he' is 'hetavern'.
'hetavern' with letters rearranged gives 'thanever'.
'better'+'thanever'='BETTER THAN EVER'
