Irish raiders Casamento and Dunboyne Express feature among a final field of 10 runners in the Racing Post Trophy at Doncaster on Saturday.
Mick Halford's Casamento ran away with the Beresford Stakes at the Curragh on his latest start and will be ridden by Frankie Dettori, while the Kevin Prendergast-trained Dunboyne Express is unbeaten in two starts.
Aidan O'Brien saddles Master Of Hounds and Seville, while Brian Meehan's Titus Mills and Ed Dunlop's Native Khan also arrive with perfect records.
Dubawi Gold, Karam Albaari, Toolain and Zaidan complete the line-up.
The only withdrawal from the five-day stage was O'Brien's Treasure Beach.
Toolain will be one of the outsiders having suffered defeat on his sole start in Pattern company at Ascot earlier this month, but his trainer Michael Jarvis feels he is better than he showed that day.
"We don't think the Ascot run was his true running as he had been off the track since July, which is a considerable length of time," said the trainer.
"He's a big horse and we just felt he was a bit rusty that day and while this is a big ask for him, we just felt it is the end of the year and we might as well have a crack at it.
"His earlier form is pretty good. He beat Mick Channon's horse (Galtymore Lad) and he is a pretty good yardstick having run Wootton Bassett close twice.
"I wouldn't think he'd want the ground too soft and ideally I'd like it to remain as it is."
