Your Ruler sets the pace.

A Ruler that turns into a J-Ruler, a 40 to 60-card deck and magic stones that give you the will to play it.

Catalog: 10,500+ cards in 95 sets since 2014.

TCGplayer market price, in dollars, for every printing.

Deck Coach that knows the Ruler and magic stone rules.

Is it for you?

You like a deck built around one character: your Ruler.

Fairy tales and legends draw you in: Alice, Little Red, King Arthur, Kaguya…

You have cards from the early clusters and want to know what they are worth today.

Scan your Force of Will cards

Take a photo, it gets matched against the catalog (10,500+ cards in 95 sets) and goes into your collection with its printing and reference price. Full Art and Uber Rare printings are told apart from the regular one before saving.

Scanning one set at a time is faster. The scanner tips work here too.

What your Force of Will cards are worth

Rulers, Marvel Rares and Uber Rares hold most of the value. TCGJoin takes the TCGplayer market price of each printing and works out the total value of your collection for you.

If you collect several games, each one keeps its own value: what your whole collection is worth.

Force of Will in 5 concepts

Just enough for your first deck.

Ruler and J-Ruler: You start with your Ruler in play. Once its condition is met it flips and joins the fight as a J-Ruler.

Magic stones: A separate deck of 10 to 20. Each turn you call one and rest it to produce will of its attribute.

Attributes: Fire, Water, Wind, Light and Darkness, plus Void (colorless). Your stones decide what you can pay for.

Resonators: Your creatures, with ATK and DEF. Damage stays until end of turn: once it reaches the DEF, it is destroyed.

Life: Each player starts at 4,000. You win when your opponent hits 0 or cannot draw.
