Aidan O'Brien fires a four-pronged assault at Sunday's Moyglare Stud Stakes in a bid to win the prestigious juvenile prize for a record eighth time.
Subsequent 1000 Guineas and Oaks heroine Minding struck gold for the master of Ballydoyle in last year's renewal and there is plenty of strength in depth to this year's team.
Ryan Moore has presumably opted to ride the unbeaten Promise To Be True over similarly exciting stable companion Rhododendron, the mount of Seamie Heffernan.
Promise To Be True has not been seen in competitive action since taking her career record to two from two in the Silver Flash Stakes at Leopardstown in July, while Glorious Goodwood maiden winner Rhododendron gained a narrow verdict in last month's Debutante Stakes over this course and distance.
O'Brien also saddles Debutante runner-up Hydrangea and the sixth, Brave Anna, who had previously won the Albany Stakes at Royal Ascot.
Joseph O'Brien is represented by Intricately, who was third in the Silver Flash and the Debutante Stakes.
The Mick Halford-trained Rehana beat Rhododendron comfortably at this track back in June, but the tables were turned in the Debutante, with Rehana only fourth.
Halford said: "We have a bit to find on her last run, but she worked very well the other day and we're very happy with her at home.
"I think good ground is the key to her, so any rain that falls won't be to her advantage. If the ground were to deteriorate too much we mightn't run her, but we'll see what happens."
The seven-strong field is completed by a fascinating newcomer in the form of Dawn Of A New Era.
Jim Bolger's filly is pitched in at the deep end for her debut, but is bred to be top-class as a full-sister to 2000 Guineas hero Dawn Approach and Group Two winner Herald The Dawn.
