A more in-depth how-to-play guide can be found here.

SiegKrone was a trading card series that created sets based off popular anime series, such as Attack on Titan.

To start off, a player must build a deck consisting of 50 cards inside. Only four copies of a same card are allowed. The card types are split up between two kinds: character cards and skill cards.

  • Character cards are split between three colors: blue, green, and red.
  • Skill cards are used to activate abilities for character cards. They can also be used to evolve (進化) or awaken (覚醒) character cards.

To use both types of cards, a player must use Cost, a limited point system used to also to evolve, awaken, and attack.
