Galway Hurdle heroine Missunited reverts to the Flat for the Ardilaun Hotel Oyster Stakes at the Ballybrit circuit on Monday.
The mare gave Mick Winters his second successive victory in the big handicap over timber last month, having proved she belongs at this Listed level by occupying the runner-up spot on three occasions this year.
Last year's winner Chamonix is one of three Aidan O'Brien representatives, but of more interest from Ballydoyle is Eye Of The Storm, who finished second in a decent renewal of the Sandown Classic Trial.
O'Brien saddles a couple of well-bred newcomers in Buonarroti and Carlo Bugatti in the opening Donnelly's Of Barna EBF Maiden (4.15), but they will need to be well above average to cope with Whitey O'Gwaun.
Dermot Weld's colt was less than three lengths adrift of leading juvenile War Command on his Leopardstown introduction and has entries in the big end-of-season Group Ones.
Weld starts off Vote Often, a full sister to Prix Marcel Boussac winner Proportional, in the Irish Stallion Farms EBF Median Auction Fillies Maiden, but the standard here is set by Willie McCreery's Colour Blue, who was fourth in a Group Three two starts back.
Recent Killarney runner-up Alkali has blinkers on the for the first time and is another big chance for Weld in the Sean Cleary Memorial Maiden, while the John Murphy-trained Todd responded well to the headgear when second at Gowran Park last week and goes in the Galway Apprentice Handicap.
Flawless Filly also makes a swift return to action and tries to defy a penalty for Thursday's Clonmel success in the Maggie May's Handicap, in which Three Bells arrives in search of a hat-trick.
