However both teams have produced consistent play as the season progessed, and the ability to put on spectacular performances when needed has put them firmly into contention for this 2021 ANZ Premiership title.
Though the Mystics had already secured their grand finals position, they came out firing against the Tactix, storming out to a 35-26 lead at halftime.
But it was game on again in the third and strong defensive pressure from the Tactix bought the Mystics' lead down to just three goals to set the stage for an exciting final quarter.
Back and forth play plagued the Tactix in the final quarter and they were ultimately unable to translate their gains into much-needed goals - the Mystics punishing their mistakes with quick conversions by shooter Grace Nweke who only missed two of her shots all night.
MVP Fa'amu Ioane dominated the midcourt in the wing defence position for the Mystics, picking up a huge chunk of her team's centre passes and disrupting the flow of the ball for the Tactix in the centre third.
Tactix captain Jane Watson made significant plays for her team on defence, but acknowledged that it was their inconsistent attacking ability that saw them unable to pick up the win.
"We've been building this whole season, and I don't think we've yet given a really solid match for a whole 60 [minutes]", she said.
The Tactix will need a full 60-minute performance if they are to pull off a win against the Steel, who will be bolstered by their emphatic home crowd on Sunday.
