Team pet (6)
I believe the answer is:
mascot
'team pet' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for mascot that I've seen before include "Thing believed to bring good luck, perhaps to team" , "Good-luck item" , "Lucky charm" , "Lucky talisman" , "Symbolic figure, for a team say" .)
