There are 7 card types in the Force of Will trading card game.
Ruler

Monument of Wisdom
Rulers are cards that act as the player's avatar.
- Ruler cards are placed in your Ruler Area at the start of each game.
- A Ruler mostly defines your deck type and play style.
- During the Call Phase, a Ruler may be
Rested to call the top of the Magic Stone Deck into your Magic Stone Area.
- A Ruler has certain Abilities that may be used to give you an advantage.
- In your Main Phase, a Ruler may also pay their Judgement condition while in Recover state to do Judgement (also known as [J-Activate]). The Ruler card is then flipped over to its other side to reveal the J-Ruler.
- This can't be done on the first turn.
J-Ruler

- A J-Ruler's [Enter] Ability will always activate.
- When a J-Rulers that has 0 DEF or less is destroyed, it doesn't go to the graveyard, it is sent back to the the Ruler Area, keeping the J-Ruler side up. The J-Ruler then loses all its abilities and its ATK and DEF. (It may however still rest and call Magic Stones)
- J-Rulers can't be targeted by Spells or Abilities that target a Resonator, but can be targeted by cards that choose a "J/Resonator".
- A J-Ruler cant use abilities requiring it to
Rest on the turn it was J-activated from its Ruler side.
