How come Yu-Gi-Oh! can collaborate with Type-Moon?This Type-Moon game is quite well-made; isn't it a bit of a waste to use it for playing cards?I'm here to play cards, what do you want?With this much bleeding, how did your game pass censorship?!Why did they even make a visual novel system?!What?!

They are essentially card substitutes for battles and will not include cards from the Yu-Gi-Oh! series.It's not a traditional Yu-Gi-Oh! story; it's just using the card game to bring out related Servants and characters to play.
