Trainer Bryan Guy is dismayed by claims his filly Stroak is not brilliant enough to win Saturday's $2m Magic Millions Classic on the Gold Coast.

Stroak is currently at $12 in Queensland's richest two-year-old race on the back of two early season wins and an unlucky second to Classic favourite Unencumbered in the B J McLachlan Stakes at her previous start.

She has blown from $9 after several experts and punters on social media have expressed doubts Stroak can muster the leg speed to sprint home in what is traditionally a 1200m dash.

Guy believes Stroak could develop into a VRC Oaks (2500m) chance in Melbourne in November.

But he also thinks she will run a mighty race in the Magic Millions.

"Everyone can have an opinion, but I can't agree with them. I'm confident she can be in the finish on Saturday," he said.

Guy believes blinkers will make a difference.

"She has gone terrific in them in track work. Going into a big race you want everything to be well and to this stage it has been plain sailing."

Stroak is by Real Saga, the sire of last year's Magic Millions winner Real Surreal.

Michael Cahill rode her and likes his chances of backing up on Stroak.

"Michael said he would ride her weeks ago and has remained confident since then," Guy said.

Stroak has more than recouped the $80,000 she cost and if she goes well on Saturday she will come into the reckoning for the $3.5m Golden Slipper at Rosehill on April 5.

"We will just wait and see how she goes. She is paid up for the Slipper but she also looks a nice horse for the Sires-J Atkins double in the winter," Guy said.

Guy's decision to clear out some of his older horses and bring more yearlings into his stable is bearing fruit.

"We got 20 yearlings who are now two-year-olds and we have a few nice ones to race yet," he said.

The trainer has been in form with seven runners on Sunday for two winners, two seconds, a third and two fourths.

Unencumbered heads the Classic betting at $3.80.
