Card type may vary, and is effected by spells, ect

counts as a deck of cards. 
each card does 1d4 slashing damage at base 
+2 if proficient with a deck of cards
+2 per charisma modifier 
may throw one card at level one
two cards at 5
three cards at 6
per action

if the character has spell slots, they may use a spell slot of 1st or higher to inscribe a spell of their spell list into the card until it is thrown. 
throwing a inscribed card counts it as spell, and ignores physical resistances.
depending on the spell inscribed, it may have an effect on the target it is throw at (Dex throw) if landed. 
Ex: "charm person" my charm a creature, or Fireball would cause the same explosion 

in addition, the character can use a spell slot, if they have one, to throw more cards equal to that spell slots level

cards thrown, unless picked up (reverts them to normal playing cards until the character drops them, in which the return to the owner) will return to the owner after 2
