Aidan O'Brien will saddle Camelot and Learn as he bids to land the Racing Post Trophy for a sixth time at Doncaster on Saturday.
Camelot heads the ante-post market, despite having only a Leopardstown debut success under his belt, while Learn's only victory from three starts came at the same venue.
There is a third Irish challenger in the shape of Jim Bolger's Zip Top, who was third to Crius in the Tattersall Stakes at Newmarket last time out and was added the race on Monday.
Godolphin rely on impressive Newmarket maiden winner Encke from Mahmood Al Zarooni's stable, another supplementary entry, while the John Gosden-trained Fencing and Jeremy Noseda's Talwar complete the line-up.
O'Brien's son Joseph takes the ride on Camelot, who is an 11-8 shot with Irish bookmakers Paddy Power, while Colm O'Donoghue will be aboard Learn.
