A shoulder injury suffered by star forward Jake Waterman rubbed salt into the wounds as Waalitj Marawar was outhunted and outclassed by Kuwarna in a 66-point loss on Sunday.
In a match played in a swirling breeze, Kuwarna led by just four points midway through the second quarter before piling on 10 of the next 12 goals to set up the 19.14 (128) to 8.14 (62) win.
There were few winners across the ground for the Eagles. Waterman had been dangerous with three goals before his shoulder was dislocated in the final term.
Jack Graham tried hard with 18 disposals and eight tackles, while Sandy Brock impressed again - blanketing Darcy Fogarty - and Tyler Brockman had one of his best games for the club with 16 disposals, four clearances and a goal.
But it wasn't enough to replicate heroics of last round's stirring win over Euro-Yroke.
Josh Rachele was the star of the show with five goals for the home team, while Jordan Dawson tallied 27 disposals, eight clearances, two goals and 602m gained.
The Crows were error-riddled early against the Eagles, but once they hit their straps they were simply unstoppable.
Reilly O'Brien (45 hitouts) was the dominant figure in the ruck, while Izak Rankine (23 disposals, six clearances, one goal) was a creative spark.
Kuwarna kicked four goals to three with the aid of the breeze in the first quarter, with Waalitj Marawar's intense pressure hard to shake.
Waalitj Marawar won the territory battle in the second quarter, but it was Kuwarna's efficiency up forward that proved the difference.
The Crows' lead extended to 23 points late in the quarter when Riley Thilthorpe kicked his second goal of the match.
But when Waterman nailed Josh Worrell with a brutal holding-the-ball tackle and then converted his 48m set shot after the half-time siren, the margin was back to a more manageable 17 points.
However, the third quarter became an avalanche of goals as Kuwarna clicked into gear.
The Crows kicked 7.7 from 23 inside 50s – including two goals in the space of a minute from Rachele – as the margin swelled to 57 points by the final change.
Tempers boiled over in the dying minutes when Eagles recruit Liam Baker pushed his forearm into the back of James Peatling's neck while the Crow was face down on the ground.
The incident sparked a major melee that is likely to attract plenty of fines.
Waalitj Marawar returns home to face Geelong on Sunday in a marquee WA Day Eve clash at Optus Stadium.
