Former Castleford half-back Jamie Ellis was the hero for Huddersfield as they brought the Tigers back down to earth with a bump following their 42-14 rout of Wigan.
While most eyes were on one-time Castleford favourite Craig Huby as he faced his home-town club for the first time, his former Tigers team-mate Ellis grabbed the limelight in a drab game with the only try of an error-strewn first half that put the Giants on their way to an ultimately convincing 22-0 victory.
The Tigers, led for the first time by Luke Dorn in the absence of the injured Michael Shenton, were a shadow of the side that humiliated Wigan as they went down rather tamely to a fourth defeat in five games.
Huddersfield, who have improved gradually after a shaky start to the season to climb to fifth in the table, defended superbly and in skipper Danny Brough had someone able to supply a rare touch of class to the otherwise dull proceedings.
In fact an eminently forgettable match will best be remembered for the wing duel between Castleford's 'Tank on the Flank' Justin Carney and the tigerish Jermaine McGillvary.
Carney managed to knock Huddersfield's towering prop Eorl Crabtree flying with one of his devastating trademark hand-offs but he could not get the better of his diminutive opposite number, who was named the Giants' man of the match before he scored the last try.
Ellis was one of the worst culprits of an error-strewn first half but he made amends two minutes before the break when he slipped the attempted tackle of Oliver Holmes 20 metres out to score the first try, which Brough goaled.
It was frantic at times but neither side could find the finishing to match their enterprise with chances going begging at both ends.
Giants centre Joe Wardle failed to finish a break by full-back Scott Grix but looked to have made the most of Ellis' 40-20 kick when he forced his way over on 15 minutes, only for video referee Phil Bentham to rule out the try for a knock-on.
At the other end, Castleford substitute Matt Cook was held up on his back and winger James Clare was bundled into the corner flag as Huddersfield's magnificent defence held firm.
The game was still evenly balanced at the break but the second half was only three minutes old when the home side increased their lead through impressive substitute forward Ukuma Ta'ai, who proved unstoppable from 10 metres out after charging onto Brough's short pass.
Brough's second goal made it 12-0 but he was wide with a drop-goal attempt from in front of the posts midway through the second half which would have made the game safe.
It mattered little, however, for the Giants were able to soak up all that their visitors threw at them and clinched the win on 62 minutes when Brough re-gathered a loose ball from Grix and got winger Aaron Murphy over for their third try.
Brough increased his side's lead with a penalty before Huddersfield created an overlap to get McGillvary over for a deserved try.
