Players cast seers adrift (9)
I believe the answer is:
actresses
'players' is the definition.
(actress is a kind of player)
'cast seers adrift' is the wordplay.
'adrift' indicates an anagram.
'cast'+'seers'='castseers'
'castseers' is an anagram of 'ACTRESSES'.
(Other definitions for actresses that I've seen before include "Stage performers" , "Starlets" , "Female impersonators" , "Girls in play" , "Female thespians" .)
