Four slot restriction.

Knowledge is the ultimate card.

​In a world where humanity is trapped behind fortress walls and beast tides devour entire nations, your deck structure is your life. Slot the wrong cards, and you die.

​Seth spent a lifetime studying card synergies, elemental  synergies, and the lethal mistakes young fighters make when building their decks. But knowing the system couldn't save him when the Primordials attacked.

​Given an unexpected second chance at youth, Seth regresses to the beginning of his journey. With his soul deck reset, he has the rare opportunity to build his deck right from day one.

​No wasted slots. No bloated builds. Just cold, calculated synergy.

​But saving humanity will require more than just personal power. The Primordial seals have failed, the monsters are organizing, and the true mastermind hiding in the dark is watching.
