'this beats paul's cryptic rubbish at a local level? on the contrary' is the definition.
The definition suggests a singular noun which matches the answer.

'this beats paul's cryptic rubbish at' is the wordplay.
'this beats' is an anagram indicator.
'cryptic rubbish at' becomes 'tor' (I can't justify this - if you can you should believe this answer much more).
'pauls' with letters rearranged gives 'pulsa'.
'pulsa'+'tor'='PULSATOR'
