Hull KR coach Tony Smith described it as "enormous" for the club as his side produced one of the biggest upsets in Super League play-off history to crush his old club Warrington and move to within 80 minutes of a maiden grand final.
The shock 19-0 result also brought to an abrupt end the four-year reign of his successor Steve Price, who will return to Australia with the big prize still eluding him.
The Robins' reward is a semi-final against League Leaders' Shield winners Catalans Dragons in Perpignan next Thursday while defending champions St Helens will host Leeds 24 hours later to determine the make-up of the October 9 title decider at Old Trafford.
"It's fantastic," Smith said. "We've been trying to break into that.
"It's enormous for our club. Probably not many people gave us much of a chance.
"I'm really pleased for the owner, it's been a long time between drinks. I like the attitude of my guys, they pulled together for each other."
Hull KR , led by former Newcastle NRL star Shaun Kenny-Dowall, defied the absence of nine senior players to condemn the Wolves to a third successive home play-off defeat and leave them still looking for a first grand-final triumph.
Their hero was former Hull and London Broncos half-back Jordan Abdull, who underlined his Man of Steel credentials with a masterful display, capped by a try, three goals and a drop goal.
"He ran the show," said Smith. "This has been coming for him. He's had some really strong performances over the years but they're coming regularly for him.
"That's what Man of Steel is about, doing it consistently. Jordan's getting more confidence about him and more wisdom as he matures."
A disappointed Price, who will return to Australia with only a Challenge Cup winners' medal, was devastated.
"We got what we deserved tonight," Price said. "I never saw that coming, it's gut-wrenching to be honest.
"The amount of errors was atrocious. I think there were 21 in total and you are never going to give yourselves a chance in rugby league.
"There were so many pressure releases and we were not able to build pressure.
"I'm going to have to take the next couple of days to reflect. We played some reasonable footy throughout the season and I thought we were getting some momentum.
"We were at full-strength apart from Mike Cooper and had everything going for us but we dished out our worst performance, which is not acceptable. We got beaten in every facet."
