We're All Card Makers, So Why Can You Break Through the Limits?

Li Lei transmigrated into the world of the card game he developed, Source of Magic, and became a card crafter. The unfinished Boundary Breakthrough card pack he had been working on before his death came with him.

And so, the most demanding deck in the game arrived in this world...

[Breaking Army Blade: When attacking, temporarily set aside the target's armor card.]

[Boundary-Breaking Army Blade: When attacking, temporarily set aside the target's equipment card. If the target has fewer equipment cards than you, this attack deals double damage.]

[Fireball: Cast a fireball that deals 6 damage.]

[Boundary Fireball: Cast a fireball that deals 6 damage. If the damage does not put the target in a dying state, return this card to your hand and reduce its mana cost to 0.]

[Summon Murloc: Summon a murloc to fight for you.]

[Boundary Summon Murloc: Summon a group of murlocs to fight for you.]

Years later, Saint Li Lei the First, having united the continent, gazed down at the kingdom beneath him and asked his close advisers, "What do you think was the most important factor in my success?"

"That utterly broken deck," they all answered in unison.
