Battle Of Marengo is the star name among six Aidan O'Brien-trained entries for the Derrinstown Stud Derby Trial at Leopardstown on Sunday.
The master of Ballydoyle has saddled nine previous winners of this 10-furlong Group Two, including subsequent Epsom Derby heroes Galileo (2001) and High Chaparral (2002).
Battle Of Marengo is following a tried-and-tested route after he won the Ballysax Stakes on his three-year-old debut.
He is the general second favourite for Epsom's premier Classic, behind 2000 Guineas hero Dawn Approach, on June 1.
O'Brien also has Indian Chief, Kingdom, League Of Nations Magician and Nevis engaged in the Derrinstown at the confirmation stage.
Dawn Approach's trainer, Jim Bolger, has a formidable pair in Loch Garman and Trading Leather.
The entries are completed by First Cornerstone, Canary Row Dont Bother Me and Little White Cloud from John Oxx's stable.
The Group Three Derrinstown Stud 1,000 Guineas Trial has attracted 17 contenders, including the Dermot Weld-trained Rawaaq and Oxx's Harasiya.
Fifteen horses are currently engaged for the Group Three Amethyst Stakes on the same card.
David Wachman's Duntle is one of the more intriguing participants, along with Weld's Caponata and Ger Lyons' stable star Lily's Angel.
