Trainer Tim Vaughan believes Swnymor could be "the real deal" ahead of the coral.co.uk Future Champions Finale Juvenile Hurdle at Chepstow.
A useful performer on the level for William Haggas, for whom he earned a rating of 87, the four-year-old made an ultra-impressive hurdling debut at Newbury in December when winning by 11 lengths.
Vaughan said: "He's a horse we like a lot and he won very nicely on his first run for us at Newbury. This is a big step up in class and whether he's ready for it at this stage of his career, who knows, but he will love the ground and I think he deserves a crack at it."
He went on: "I hope he can run a big race. I think he could be the real deal."
Ruacana, a decent handicapper on the Flat for Michael Bell, made a winning hurdling debut at Catterick but takes a giant leap up in class.
Trainer John Ferguson said: "He had plenty of experience on the Flat and it was a nice performance at Catterick on his debut. I know a Grade One is a long way removed from a novice hurdle at Catterick but he has done well since, so I thought he had nothing to lose running in a race like this.
"He had experience of soft ground on the Flat for Michael Bell so I'm not too worried about that."
Paul Nicholls, who has never won the race, runs the French import Caid Du Berlais, who will be making his British debut. Being by Westerner, and having raced in similar conditions his whole life, the testing ground is unlikely to bother him.
"He's probably the highest rated of the juveniles we bought out of France and he's a nice horse who loves soft ground," Nicholls told Betfair.
"I had it in my mind that we'd aim him at one race and that was the Grade One at Chepstow on Welsh National day. He's a grand little horse who jumps well and hopefully he'll run a big race."
