The two Yorkshire rivals clash at Wembley on Saturday in the League One play-off final.
Bradford-born Ward, 20, has supplied much of the ammunition for team-mate Jordan Rhodes, whose 40 goals this season have made him one of English football's hottest properties, and expects the striker to snuff out the Blades' chances of an instant return to the Championship.
Ward, who will appear in his third successive play-off final, said: "Jordan's one of the nicest guys I've met in football. He's so modest. To be ripping the league apart by scoring that many goals this season has been unbelievable and to remain so humble about everything is amazing.
"It shows what kind of a person he is and he has to be the best goalscorer I've played with. You put him in the positions and it's in the back of the net.
"He's got fantastic ability and is great to play with because you know if you're going to whip a ball in, Jordan's going to be on the end of it nine times out of 10."
The Blades had been fired for most of the season by the goals of Ched Evans, until the Wales international was jailed in April after being found guilty of rape.
Evans' 35 goals in 42 appearances this season kept Danny Wilson's side in the hunt for automatic promotion, but his absence coincided with a late wobble that saw Sheffield Wednesday pip them to second place.
Ward added: "They've lost their main striker, but they've still got a great side. We've watched them in both their play-off games, but I prefer to focus on my own game and worry about the job I've got to do.
"Obviously it's a massive loss for them, but we've got to focus on our own game and hopefully Jordan will keep firing on Saturday, I'm sure he will."
Ward appeared in the 2010 League One play-off final for Swindon, managed at the time by Blades boss Wilson, and was a member of Lee Clark's Huddersfield side which lost 3-0 to Peterborough at Old Trafford in last season's final.
"It will stand me in good stead," Ward added. "I know what to expect, but I don't want to come away with the same feelings.
"There's quite a few of us who were in that dressing room last year, who don't want to come away with that feeling of devastation. We're eager to put that right.
"It would be the high point of my career without a doubt. It's something I've been close to achieving for the last two years. To win at Wembley and win promotion for Huddersfield would be by far the biggest achievement in my career so far."
The Blades have yet to win a play-off final, losing out three times in the Championship - 1-0 to Crystal Palace in 1997, 3-0 to Wolves in 2003 and 1-0 to Burnley in 2009 - but skipper Michael Doyle insists that will have no bearing on Saturday.
"This will be the first time I have experienced a play-off final, but I'm well aware of what is at stake," he said.
"We'll pay Huddersfield respect because they're a really good side, it will be tough, but we're confident of coming out on top.
"A lot of the squad hasn't been through the heartache of the play-offs and everyone is positive and focused on the challenge.
"At the start of the season we wanted to be in a position where we had the chance of returning to the Championship and we've one game to win to achieve that goal."
