I have no idea about Hanafuda though, perhaps you can share it here in the thread here.
I might do that.
In fact, let me talk about the basics really quickly right here:
In Hanafuda, there are twelve suits of four cards each that are based off of seasons/seasonal plants.
You create pairs of cards by matching seasons, and you use the cards you get to make Yakus, which are basically matches.
In Hanafuda, one player starts with 10 points and tries to get up to 50 to win the game. Their opponent attempts to score points to make their score go down to 0, making them lose.
To score points, one must match up Yakus, which are partially determined by the kind of card you have, as I stated before.
In each suit (except for the final two), there are two plain cards, one ribbon card, and one animal card or bright card (first has a bright, second has an animal, third has a bright, etc.). The exceptions to this are the Willow and Paulownia suits, which have one plain, one ribbon, one bright, and one animal; and three plains and one bright, respectively.
The ribbons happen to be even more sorted, into red, blue, and poetry ribbons, which are important for scoring.
The Yakus are as follows:
Five animals gets you one point, and each additional animal after the fifth gives you another point.
Five ribbons gets you one point, and each additional ribbon after the fifth gives you another point.
Matching all three of the blue or the poetry ribbons will give you six points.
Having the Boar, Deer, and Butterfly cards matched gives you five points.
Matching three brights without the Rain Man card gives you six points.
Having four bright cards, including the Rain Man card gives you eight points.
Having all five bright cards gives you fifteen points.
Matching all of a season while that season is in play (it rotates from the first, which is pine) will give you four points.
Matching 10 cards that are plains will give you one point, with each additional plain card giving another point.
Also, the animal card of the chrysanthemums is partially a wild card, acting as a plains card as well as an animal card.
If neither player gets any Yakus, the dealer (who is chosen by random for the first round, but is whoever won the last round after that) gets six points.
That's basically all you need to know about hanafuda. You need to get used to the cards, of course, but that's the gist of it.
Now, that could translate to smash in an interesting way. If you use attacks based off of, say, an animal five times repeatedly, maybe the damage that you're dealing will go up. Just an idea, but it could be interesting.
