Schwarz Rot Asse by Jochen Zmeck

Handbuch der Magie (German book) by Jochen Zmeck
Page 120 et seq.

Personal Comment: Basically a color change, Two reversals and the black aces finding the red mates. So naturally this is a little routine that people tend to appreciate. It has surprises, flows naturally and is easy. If I had to teach someone slightly advanced card magic this is the routine I would go for. It's practical (the setup is within reasons) and with little tweaking this could greatly benefit from advanced moves.

Difficulty 2/5
