The Tactix left the make-up of the ANZ Netball Premiership finals series up in the air after upsetting the Northern Mystics 57-46 in Auckland.
With nothing to lose and in their last game of the season, the bottom-of-the-table Tactix showed scant regard for the formbook as they dismantled the previously in-form home team.
The Mystics looked a shadow of the team they have presented in recent weeks and now have an anxious wait after opening the door for WBOP Magic to sneak past them and into the Elimination Final.
Putting on their best game of the season, a passionate and gritty Tactix held their poise, veteran campaigner Anna Thompson and feisty defender Temalisi Fakahokotau were standouts for the visitors.
Apart from Mystics defender Anna Harrison missing from action with a minor injury niggle, there were no surprises in either line-up.
The Mystics now have an anxious wait after opening the door for Waikato Bay of Plenty Magic to sneak past them and into third place and the elimination final.
