so you basically use it in an ambitious card routine
Exactly. The additional phase adds something to the plot. This is why the classics are classics. To do what you are doing, you could use a tilt followed by a top change (recognizing that a top change is more difficult to pull off on video where the focus is your hands).
For what you are doing, Eddie Fechter's "Be Honest What is It" which can be found in "Fechter: The Magic of Eddie Fechter" by Jerry Mentzer is a much stronger version. I also like it when the top card is given to the spectator to stick in the face up deck as an "indicator card" to try and find their own card and when they don't find their card, it is revealed that the indicator card is their card. Both add the "something more" that increases the entertainment value.
In thinking about magic effect, try to focus on what the spectator sees and remembers and think about what magic is being demonstrated. In an ambitious card, the audience sees the card inserted in the middle and it rises to the top. What does the audience see in your effect and what is the magic that happens?
A couple of final thoughts on your card handling. First, slow down. Sometimes we rush through sleights for fear of being caught. Trust you technique and go slow. Second, use a more open handling of the cards. The default position should be your hands are apart with your right hand and the cards in the center of your body. Your left hand should only approach and touch the card when necessary. Relax your grip in your right hand and fold your fingers down a bit. When your left hand is moving away from the cards turn it palm up.
