Decks: Use matching decks with one copy of each agreed creature, a Skill 100–199 starter and at least three other cards. The demo includes all 60 current creatures per side.

Health: One wound represents 100 damage. Wound spaces equal Health divided by 100, rounded up. When all spaces fill, discard the creature immediately. Wounds and shields travel with it; healing removes wounds.

Skill: Deployment costs one action at 100–199, two at 200–299, or three at 300–399, paid together. Deploy into an empty friendly lane, exhausted.

Readiness: Actions other than deploying cost one action and exhaust the ready creature using them. Exhausted creatures still defend and keep passive abilities. Unused actions expire. Empty decks do not reshuffle.

Speed: 100–199 reaches a neighboring lane; 200–299 reaches either other lane. Move to an empty lane or swap with a teammate. Relay swaps with a teammate in range, then the initiating creature attacks an enemy in its new lane. The partner keeps its readiness.

Abilities: Follow each creature’s text. Ability attacks use normal combat. Ability wounds ignore Defense but use shields unless stated otherwise. A defeat awards the opposing side a Spark even when self-inflicted. Resolve all bonuses and self-wounds before checking victory.
