Good hand for throne action? (5,5)
I believe the answer is:
royal flush
This could be a double definition.
'good hand' is the first definition.
(I've seen this before)
'throne action?' is the second definition.
The definition suggests a singular noun which matches the answer.
'for' is the link.
(Other definitions for royal flush that I've seen before include "good deal?" , "Hand of cards" , "Top hand" , "Great hand" , "embarrassment at the palace?" .)
