One unique feature is the use of magic. For instance, the cards could be self - shuffling or have pictures that move. In some fanfictions, the players can use spells during the game to bluff or influence the outcome.
Harry Potter himself could be one of the main characters. He might be drawn into the poker game by his friends Ron and Hermione, who think it could be a fun way to unwind from their usual magical adventures.
Well, perhaps the poker game is a test of loyalty. In this 'Harry Potter fanfic', different houses could be pitted against each other in the poker game. And the winner of the game might get a special magical item that has been lost for centuries. It would be full of strategic plays and magical elements within the game.
Sure. 'The Poker Game' in Harry Potter fanfiction can have various interpretations. One interesting piece might be on Fanfiction.net where the characters play a magical poker game with enchanted cards that have spells on them. Another could be where the poker game is a cover for a secret Order of Phoenix meeting.
One idea could be that the characters play poker to decide who gets to use a powerful magical artifact for a day. For example, Harry, Ron, and Hermione play against the Slytherins.
Well, 'creature of the night' in a Harry Potter fanfic could be dementors too. Dementors are these dark, hooded entities that lurk in the shadows and feed on positive emotions. They are most active at night, spreading their cold and despair. In fanfics, authors might explore their origin more deeply or create new scenarios where the characters have to face them in different ways than in the original books. They are a great way to create a spooky and tense atmosphere in the fanfic.
The strategy aspect in the poker games could be fascinating. Since the characters are ninjas, they might use their ninja - like thinking to approach the poker hands. They could be bluffing in ways that are unique to their ninja skills, like Naruto might give away his bluff by being overly excited, while Kakashi could be a master of the poker face, just as he is with his Sharingan.
I really like 'A Fun Night in Hogsmeade'. In this fanfic, the characters go to Hogsmeade for a night out during a special event. There are new magical shops and attractions, and the interactions between the characters are really engaging. It gives a different perspective on the Hogsmeade we know from the books, with more secrets and surprises waiting to be discovered.
I'm not entirely sure if there is a specific 'Harry Potter kills the Night King' fanfiction. However, given the popularity of both 'Harry Potter' and 'Game of Thrones', it's very likely that some fans have been creative enough to write such a story. Fanfiction communities are full of these kinds of crossovers, but you may need to search through various fanfiction platforms to find it.
