As the Magpies' makeshift forward line lost Jeremy Howe to a groin issue, Daicos pulled the strings in the engine room during a 15.13 (103) to 5.7 (37) victory at Marvel Stadium on Sunday.
The smooth-moving ball-winner racked up 36 disposals, 17 contested possessions, seven clearances, seven tackles and a goal as Collingwood improved to 5-1-3 ahead of a clash with Adelaide.
The Magpies also secured a much-needed percentage boost, lifting nine points to push above 100 for the first time this season.

But the win came at a cost, with Howe (groin) and Harvey Harrison (ankle) hurt during the first quarter.
Former St Kilda midfielder Jack Bytel, who was substituted in for Howe on his Magpies debut, also failed to finish the match because of concussion after a collision with Jack Darling.
West Coast lost experienced defender Jeremy McGovern (ribs) and speedster Jack Petruccelle (ankle) to injuries on a dirty day.
A third straight defeat left them with a 2-7 record and third from bottom on the ladder.
Daicos had plenty of support through brother Josh Daicos (28 disposals), Scott Pendlebury (28), Jack Crisp (32) and John Noble (25) in a dominant Collingwood performance that started in the middle.
The Pies won a lop-sided clearance count 38-25, including a 16-6 annihilation at centre bounces.
Finlay Macrae and Reef McInnes kicked career-high tallies of three goals each, and Bobby Hill added two more, while mature-age recruit Joe Richards impressed on debut with 1.2 and three goal assists from 18 disposals.
Collingwood kicked their second triple-figure score of the season despite the absence of leading goal-kickers Jamie Elliott and Brody Mihocek, and fourth-ranked Lachie Schultz.
Liam Duggan (27 disposals) and Alex Witherden (30) battled on for West Coast and emerging star Harley Reid (17) took a huge early mark on Billy Frampton's back, but it was a rare highlight for the visitors.

Each of the Eagles' three first-half goals - including one to debutant Tyrell Dewar - received quick replies at the other end as Collingwood broke the game wide open during the second term.
The Pies, who kicked seven first-half goals direct from centre clearances, slammed on six majors in a 12-minute burst to take a 55-point lead to the main break.
Tempers briefly flared after the siren when McGovern hit Richards with a late bump.
Collingwood's lead reached 74 points at one point but they were outscored 2.2 to 1.2 in the final term.
