Castiel, by Casalito, only recently formed a partnership with Schwizer. The Holsteiner stallion began his international career in 2022 under the guidance of Natale Chiaudani and was ridden for a period the following year by Edouard Schmitz. Subsequently, he moved to the stables of Schwizer. In December, this combination secured a twelfth-place finish in the CSI4* Grand Prix in Frankfurt.

Both Christina (Cassirado) and Erico Hoy ( Bel Reinhart Z) are owned by Kurt and Brigitte Schreier, who also owns Castiel. Schwizer rode Christina at the international 1.50m level last year, while he competed with Erico Hoy at the international 1.45m level.
