Don Cossack is being targeted at the Dr PJ Moriarty Novice Chase at Leopardstown on 9 February.
Gordon Elliott's seven-year-old claimed the Grade One prize he has long promised when edging out Carlingford Lough in the Drinmore Novice Chase at Fairyhouse at the start of December.
That form looks strong after the runner-up landed Leopardstown's Topaz Novice Chase over the Christmas period.
Don Cossack will now go in search of further top-level honours on Irish Hennessy Gold Cup day.
Elliott said: "Don Cossack is in good form and we're aiming him at the Moriarty.
"His form is working out well, so we're looking forward to running him."
Elliott has yet to make any plans for Mount Benbulben, who ran respectably to finish fourth in the King George VI Chase at Kempton on St Stephen's Day, despite jumping mistakes which have become a feature of his career.
"He came out of Kempton well, but I'm not sure where we'll go with him," said the Meath trainer.
