How I Combined Skeleton Cards into a Lich King

[Gacha] [Necromancer] [Plot-Driven] [Summoning] [Synthesis]

This is a cruel and uncanny magic-card world, where any magic can be turned into a card as thin as a cicada's wing.

Before a throne of bones, Chen Yu lightly raises a finger, and a bone dragon ten thousand meters long tears through the clouds.

His is an ability that lets him synthesize cards: "Undead Stitching."

[Level One Skeleton Card] + [Level One Skeleton Card] = [Skeleton Warrior]

[Skeleton Warrior] + [Undead Warhorse] = [Death Knight]

He is a hacker capable of tampering with the world's underlying code.

"Draw cards? That takes too long."

"I choose... to stitch the entire world into my deck."

"Congratulations, you pulled another gold... though it's just another card I've cursed."
