Concept: You can heal with flourishes.
So, if you get a scratch for example, you can pick up the deck and perform "Phobos Deimos" and you heal your wound. The more advanced a flourish is, the bigger the wound it can heal.
Template: The Shaman
A boy and a girl seek the local shaman of a village in search of spiritual healing. The shaman welcomes the boy in his hut and tells him to lie on his back. He then proceeds to take out a deck of cards.
"This deck will allow you to visualize your spiritual demons."
Cardistry moves are shown in parallel with visuals and 1-2 cuts of the boy entering a trance.
"This other deck will give you the power to overcome your spirits." The shaman takes out a different deck of cards.
Cardistry moves are shown in parallel with visuals.
The boy is healed.
Notes
You can take this template and apply it to a family doctor session, a psychotherapy session, an acupuncture session.
Sketch
Every time Timmy hurts himself at soccer, the other classmates see him going in the bushes and coming out only after a few seconds, more alive than before.
After the 3rd time this happens, Timmy appears to have gotten a serious injury (it looks like a broken leg). Everyone sees the kid shuffle heavily towards the bushes.
The players look at each other and agree to see what's happening. They move onto the place and hear sounds coming from behind the grass. A boy motions "masturbation". The others laugh silently.
"Yo, Timmy, what you doin' in there."
The bushes are parted to discover the kid flourishing over his broken leg.
