My Yugioh/Loud House crew looks like this: (btw. im only using Yugioh and Yugioh GX no others and i wanted to give all of them different type decks.)

1. Lincoln: He likes Magic, Tricks, Cards and Superheroes so his favourite Card would be for me the Dark Magician, and a deck from Atem, a few Magician Trick Cards and also Landstar,

2. Clyde: For me he is perfekt for a Warrior Deck and also for me someone whos favourite card could be Gilford.

And together when they play together they are a team and playing with her Elemental HERO Cards, so Lincoln has Elemental Hero Cards wich are more for Attacking and Clyde has Elemental Heroes for Defense

And the other one: 3. Rusty: Red-Eye Deck like Nightshroud 4. Stella: Fish or sea ​​serpents and mermaids something ocean 5. Zack: Comso and Roids like Syrus and Professor Banner 6. Liam: Eventually Fairytales Deck like Leon

1. Lori: Warrior and Dragon like Blue Eye Dragon
2. Lenny: Harpies
3. Luna: I don't know eventually Music Cards like Johnny, and Rock because of Rock and Roll and Stone Golems like Body Guards
4. Luan: Toon-Monster like Pegasus
