These full brothers combine the blood of Cornet Obolensky, Mylord Carthago, Darco (via Non Stop and Viking), DIAMANT DE SEMILLY and Galoubet A (Almé).
Their dam line has produced numerous top performers, including Tam Tam Semilly (CSI 1.55m), Jisco du Prieuré(2024 French Vice-Champion 5yo geldings), As You Like Semilly (1.45m), as well as the dams of Dream Day Melp (9th WC CSI4* São Paulo 2025), Broadway Semilly (1.45m), Kenya RM (CSI5* 1.50m), and their second dam, who produced Diabolo de San Isidro (CSI 1.50m) and Fantastic Mr. Fox, formerly Fantastic San Isidro (CSI 1.45m).
