Since he represents Nintendo non-video game products I guess he can have something like this :
Neutral B : Love tester
Mister Hanafuda launch one of the metal balls from the Love Tester toward him, if the ball hit a foe the ball will wrap around him/her, he/she will be unable to go away until one of them get hurt or if Mr Hanafuda use this attack again, if he do he will use the love tester like a fishing rod and send his opponent flying in his direction.
Up B : Ultra hand
Your basic tether reccovery attack except that he will act like the second part of the Love tester if it hit another character.
Down B : Chiritorie
Mr Hanafuda will put a chicoritie on the ground, it will not move until an opponent gets too close, it will then begin to chase him/her, if it succeeds to touch him/her it will immobilize him/her for some seconds, in any case the Chiritorie will disappear sometimes after being summoned but not activate, fail to grab the opponent after some seconds, destroy by attacks of if Mr Hanafuda put another somewhere.
Side B : Lefty RX
A little car who will go straight forward at high speed at the cost of not being to not being able to turn around or jump, will disappear once it hit something or fall to his demise.
Final Smash : Kôsenjû SP Series
Works pretty much like Zelda's Light Arrow.
