Butterflies could secure some valuable winning black type in Wednesday evening' s Naas feature but perhaps the most interesting runner on the card will be a regally-bred newcomer in the finale.
Goldrush is a daughter of Frankel and the multiple Group One winner Alexander Goldrun who made €1.7 million at the 2015 Goffs Orby Sale.
She will carry the China Horse Club colours when she makes her racing debut in a €15,000 mile maiden. Goldrush's trainer Jim Bolger trained the dam to win five Group One races in four different countries.
Butterflies boasts a glowing pedigree herself and if she can land the Listed Oaks Trial it will make her an even more valuable broodmare prospect.
She looked to have secured a Group Three tag at Cork earlier this month only to be 'mugged' close to the line by the surprise winner Santa Monica.
Butterflies drops back to 10 furlongs here but first-time blinkers could sharpen her up and she can confirm Cork form with her stable companion Key To My Heart.
Yulong Xionghu carries a first-time hood in an earlier three-year-old maiden and Shane Foley's mount should be tough to beat if stepping up from a promising Limerick debut behind True Valour.
