No bowler enjoys using the pink ball as much as the left-hander, who claimed 4-37 in the first innings at Adelaide Oval. His record now stands at 50 wickets — 18 ahead of next-best Josh Hazlewood — at an average of 18.10 in day-night tests.
"We've got a bit of a luxury of having played eight tests and (six) have been here," Starc said. "I don't think I've nailed it. But we've all got a certain plan to it."
Cameron Green was also influential for Australia on Saturday with 2-24, claiming the key wicket of Joe Root and ending a 138-run stand between the England skipper and Dawid Malan.
Green beat Root twice in the over in the lead-up to catching his edge on 62 before Starc had Malan caught in the slips six overs later for 80.
Root is the world's top-ranked test batsman. He's only the second test captain to score more than 1,600 runs in a calendar year — 1,606 in 2021, behind the 1,656 of South Africa's Graeme Smith in 2008.
But he's never scored a test century in Australia following his 62 in Adelaide and 89 in the second innings of England's nine-wicket loss in the Ashes opener in Brisbane.
Malan, who has made 80 and 82 in his past two test innings, said after Saturday's play: "It's big runs ... big hundreds that win you test matches."
"Last test match we were in a position, both myself and Rooty, to score hundreds and we didn't do it," Malan said. "And we were in the same position here. That is something we need to do better ... if someone gets in, to make sure we get that big hundred."
After claiming Rory Burns' wicket under lights on Friday night, Starc also had Jos Buttler out for a duck as part of an 18-over period of 4-19 for England.
It continued a poor game for wicketkeeper Buttler, who dropped century-maker Marnus Labuschagne twice, including on 21 before he went on to post 103.
Australia's Nathan Lyon also had a big influence, taking 3-58 on a pitch where England opted against playing a specialist spinner.
Australia will now likely try to bat through until the twilight session on Sunday before leaving England with the best part of four sessions to save the match on the final day Monday.
A loss for England in Adelaide would leave the visitors 2-0 down in the series and needing to win all three remaining tests to win back the Ashes.
