Though by no means as freakish as Warne nor an all-round talent in the class of Richie Benaud, the bowler-batsman-captain whose 248-wicket tally he passed on day one in Dhaka, Lyon never gives anything less than his most unsparing effort.
David Warner was given a reprieve by the third umpire from a lbw decision off Mehedi Hasan, but the spinner trapped the left-hander the same way with the very next ball.
Usman Khawaja - whose return to the Test side has started horrendously - was caught short of his ground after pursuing a mindless single, adding to the early-innings woes of the tourists.
Meanwhile, Australia announced their squad for the first Test, with all-rounder Ashton Agar being recalled after a gap of four years, while southpaw Usman Khawaja will be making the cut after seven months.
Bangladesh captain Mushfiqur Rahim won the toss and opted to bat at the rain-soaked Sher-e-Bangla National Stadium, only to find Cummins embarking on a fierce spell of fast bowling.
With Shakib playing his strokes at one end, Tamim looked defensively solid at the other.
Lyon was expected to lead Australia's spin attack in the Bangladesh Tests as the visitors play their first series against the hosts in more than a decade. To overtake him in the wickets column is something pretty special.
Tamim Iqbal struck his 23rd half-century in Test cricket
Shakib, Mehedi and Taijul took all 20 wickets when Bangladesh recorded their first-ever Test win over England by 108 runs in October.
Tamim, who is Bangladesh's highest scorer in both Test and ODIs, showed he belongs in a class of his own as he did not lose his composure while seeing off the pacers during the crucial early period.
It also elevates him to eighth (replacing another ex-leggie, Richie Benaud) on Australia's honour board of Test wicket-takers, with the potential to snatch seventh-place from Jason Gillespie (259 wickets) by the time this tour of Bangladesh is done.
Australia's most recent trips to the subcontinent ended in defeat.
Bowling first on an overcast morning in Dhaka, Cummins' impact was nearly immediate.
Soumya Sarkar (8) was dismissed first, edging one low to the slips from close to the body. The opener was not as lucky two balls later as he clipped a Cummins delivery straight to Handscomb at gully to depart for eight.
Cummins struck again in his next over as he had Imrul Kayes caught behind for a six-ball duck.
Bangladesh had run out of reviews, however replays suggested that the ball had hit Hasan's pad rather than the edge.
