Concept
A place where cardists come to strengthen their hand muscles through different card flourishes.
Ideas
In one corner you have individuals performing sets of the "Twirl" Flourish and counting out loud, "97, 98, 99, 100!"
"L" Cuts performed while doing sit ups.
Punching the sand bag with one hand and performing "Piano Cuts" with the other.
We see somebody doing weightlifting but the weight is made out of card decks stuck to each other.
Plot Idea
Someone is walking down the street, playing "Pokemon GO". The guy starts walking to where the rare pokemon is. Walks up a flight of stairs. Opens a door. And starts walking through the Cardistry Gym without paying any sort of attention to what is happening around him. When he's about to catch the pokemon, the buffed cardists pay attention to him and his challenge. Finally, the guy catches the pokemon and everyone is happy for him. By the time the kid notices he is in a gym, the Cardistry Gym appears to be like any other gym out there. CAMERA FILMS FROM ABOVE, CLOSE TO THE CEILING. The kid says goodbye to the fellows and walks out the door. We see the gym resume his cardistry gym exercises.
