Cilaos Emery made a pleasing return to action in the Poplar Square Chase at Naas.
Last seen beating subsequent Arkle-winning stablemate Duc De Genievres on his only previous outing over fences, he made only one semblance of an error on his way to victory.
Sent off the 4-9 favourite, Paul Townend was content to track Ornua, a Grade One winner at Aintree, before sprinting clear before the second last.
Betfair cut him to 11-1 from 16s for the Champion Chase.
Assistant trainer Patrick Mullins said: “That was very impressive for a horse with such little experience. Ornua is obviously a Grade One winner and we were getting a lot of weight.
“He wasn’t going to be easy to place this year with just one run as a novice. I’m not sure what the plan is now, but he has a lot of ability and will probably be kept to two miles for the moment.
“He’s only had two runs over fences and maybe it would be best to take baby steps and get more experience into him.
“Today was an ideal race with just four runners and they were well spread out. His jumping has always been good.”
Mullins enjoyed a treble on the day with two useful novices starting their seasons in fine style.
Elixir D’Ainay (13-8 favourite) only made it to the track once last season, but pulled a long way clear with Longhouse Poet in the Cavan Developments Home Builders Supporting St. Marys GAA Maiden Hurdle, winning for Mark Walsh.
Tornoado Flyer (5-4) was smart in bumpers and over hurdles and won the Mongey Communications Beginners Chase to give Townend a double – despite a bad blunder at halfway.
“We didn’t get a clear run with him last season. He’s a high-class horse and I think he can only build on that. He had a couple of blows and he was gassy early o,n but he warmed up to it,” said Townend.
Surin ran out a clear-cut winner of the Fishery Lane Hurdle for Gordon Elliott and Luke Dempsey.
Making full use of her fillies’ allowance in the testing conditions, Surin (9-2), who fared well in the best company last year, looked set to be swamped at the second last.
Quartz Du Rheu, Gardens Of Babylon and Tiger Tap Tap all loomed up to challenge, but the filly powered clear to win by seven and a half lengths.
Elliott said: “Luke gave her a good, positive ride. We knew she would stay well, she had a run and she was fit. She’s a good mare and has improved from last year and grown a lot. It was a good performance.
“I’m not sure where we will go now, but she will be aimed at those mares’ hurdle races. She’ll have a few easy weeks now and then we’ll see what happens.”
The winner was given a 25-1 quote by Paddy Power for the Mares’ Hurdle at Cheltenham in March.
Joseph O’Brien’s smart bumper performer Embittered is a 33-1 chance for the Supreme Novices’ Hurdle with Betfair after beating Blackbow on his hurdling bow.
On bumper form there was little between the two market principles, yet despite having his first run for 563 days, Mullins’ Blackbow was sent off the odd-on favourite.
After bypassing the last flight in the Irish Stallion Owners EBF Maiden Hurdle, Embittered (7-2) and JJ Slevin came out on top by half a length.
“He was a decent bumper horse and he jumped well. He did well to win as I thought he’d want the race,” said O’Brien.
“He could go for the Royal Bond.”
