Fairyhouse's card starts with a bang as Willie Mullins and Aidan O'Brien lock horns in the opening Winning Fair Juvenile Hurdle at 1.25.
Champion jumps trainer Mullins saddles three runners in the Grade Two affair, with Ruby Walsh opting to ride easy Punchestown winner Adriana Des Mottes.
That takes little away from Abbyssial, who aready has two wins to his name, and All Pepper, who makes his debut on these shores after two French wins.
O'Brien has Plinth, whose jumping let him down slightly when third in a Grade One last time.
Mullins also has strong claims on the other Grade Two on the card, as On His Own bids to follow up an emphatic Gowran win in the At The Races Bobbyjo Chase.
Lion Na Bearnai comes into the race on the back of a recent success as well, while Mount Benbulben was not disgraced in the King George at Kempton and is another to note in a competitive heat.
On what could be a lucrative day for Mullins, he saddles decent bumper performer Beluckyagain in the www.fairyhouse.ie For Special Offers Mares Maiden Hurdle, in which Leopardstown fifth Ellie Mia could be the biggest danger.
The Closutton maestro also has Wicklow Gold in the attheraces.com Exclusive Barry Geraghty Blog Handicap Hurdle.
A 27-length winner on his hurdling bow at Tramore, he switches to handicap company off a fair mark, though Seriatim and Star Neuville are old hands in this sphere.
Mullins also saddles Kalmann in the Irish Stallion Farms EBF Beginners Chase, the five-year-old stepping up in trip after plugging on for third on his first attempt over fences.
He faces a very smart operator in Si C'Etait Vrai, though, and Dessie Hughes's charge will be out to atone for a last-fence fall when in front here.
Mullins' final runner is Westhorpe, who takes on seven fellow newcomers in the Ian Smith Memorial (Pro/Am) INH Flat Race.
