Concept: In order to summon something like an object or a living thing, flourishers must execute a move with the name of the thing they want to summon.
Example: if I need some worms for my fishing, I will take out my deck and execute the "Worm" flourish in order to summon 1 worm.
Background: There are two types of flourishers: there are creators and there are performers. The rule is that one cannot summon something using a move he has created himself. One must always use another's move. This rule has been created in order to keep a balance going.
This could be transformed into a series where a character that is new to flourishing learns the ropes of the world.
