The Baggies will face the first of the three newly-promoted teams on Saturday, November 2, when they host Crystal Palace, with a trip to Cardiff and a home date with Hull to follow in December.
And Brunt has tipped the trio to make it another testing top-flight programme.
"They've worked hard to get up but the real challenge now is staying up," he insisted to the WBA website.
"There are three good managers in charge of those teams.
"Steve Bruce has been there and done it before, as has Ian Holloway, so they'll both know what to expect.
"Malky Mackay has done well in his first couple of jobs and I'm sure, with Cardiff's owners, they'll have a few quid to spend as well.
"It's going to be a tough league this season."
