Willie Mullins is responsible for four of the 11 horses confirmed for the Powers Gold Cup at Fairyhouse on Sunday.
Heading the quartet is Champagne Fever, narrowly beaten by shock winner Western Warhorse in the Arkle at the Cheltenham Festival last month.
The champion trainer could also saddle Ballycasey, Felix Yonger and Mozoltov, although each of the four contenders also hold entries at the upcoming Punchestown Festival.
Gordon Elliott could saddle Don Cossack, who chased home Holywell in the Mildmay Novices' Chase at Aintree's Grand National meeting.
Mick Winters is set to be represented by stable star Rebel Fitz after he made a winning return from a winter break over hurdles at Cork recently.
Jim Culloty's Kim Muir winner Spring Heeled, Dessie Hughes' hat-trick seeker Bright New Dawn and the Ted Walsh-trained Foxrock could all feature.
The entries are completed by Noel Meade's pair Road To Riches and Mullaghanoe River.
