The importance of the match was evident from the outset, as the teams delivered an exhibition of polished netball through a high-scoring opening stanza.
Shooter Cathrine Tuivaiti looked in the mood to torment her old team, helping the Pulse build an early four-goal buffer.
Tuivaiti notched a perfect 14 from 14 as the teams went to the first break all tied up at 17-all.
The Mystics began to make some ground defensively in the second quarter, with goal keeper Storm Purvis continually hunting for turnover ball and wing defence Anna Harrison causing all sorts of strife for the Pulse attackers.
With Tutaia's long shot on song, the Mystics enjoyed several strong surges on the back of attacking drives from centre Samon Nathan while the Pulse lost a little of their flow and confidence on attack with errors starting to creep in.
Gaining plenty from their extra defensive hustle and bustle, the Mystics edged ahead 34-29 at halftime.
The Auckland side then began to take control in the third quarter and the Pulse were left in chase mode, unable to contain the speed and accuracy of Tutaia, Elispeta Toeava and Nathan.
The defensive line of Harrison, Michaela Sokolich-Beatson and Purvis mopped up at the other end to help push the Mystics out to a well-merited 53-41 lead at the last break.
