📖 Co-op Rules Summary

Christianity Strategy Card Game — Original / co-op vs the Evil deck

Humility (Power) & Maturity

Start at 3/10 Humility (Power). Humility (Power) is changed only by card effects (e.g. "Gain X Humility (Power)" H+X, "Resist an Ambush → Gain X −3 Humility (Power)") and by failing temptations: −1 Humility (Power) H-1 if you have any; if Humility (Power) is already 0 H0, the overflow forces a discard per point — from hand OR Cost Zone (your choice). Placing cards in the Cost Zone does not change Humility (Power).

Reach Maturity L3 on all righteous players to win. Level up Maturity by playing Maturity-type cards: each resolved Maturity card raises your Maturity level by 1 (0 → 1 → 2 → 3).

Right-click the Humility (Power) or Maturity badge to adjust either stat manually (house rules, testing, or card effects not yet implemented).

✦ Maturity Abilities — "Mature Together"

The Righteous team can unlock shared abilities. Each time all players reach the next Maturity Level (L1, L2, L3), you collectively choose one ability for the whole team — free. You may also purchase an ability by spending Cost (11 high-tier / 7 low-tier) right after your own Cost Zone phase (from the abilities bar, bottom-left).

• Benevolence / Double Resistance — any player may spend their own Cost Zone to help resist a temptation (not just the targeted player).
• Brotherly Love — redirect your next card's beneficial effect to a teammate.
• Restoration — once each time all players reach a new Maturity Level, every Righteous Player shuffles up to 15 random cards from their discard pile back into their own Deck. Recharges at every new shared level.
• ✝ Deliverance — once each time your team reaches a new Maturity Level, break up to 3 Evil Habituals in play (removed to the Resisted pile). Recharges at every new level.
• Vibrancy — flip 2 Cost Zone cards face-up after your Cost phase.
• Cost Zone Power — gained 3+ Power this turn? Draw a card straight to your Cost Zone at end of turn.
• Speed — play 1 Habitual/Maturity card at any time on your turn.
• Foresight — reveal the Evil Deck's next draws at the start of your Cost phase.

Toggle the whole system on/off in the game menu (Maturity Abilities) or with ?matAbilities=0. These Righteous abilities are also available in ⚔️ Duel mode (the lone Righteous seat unlocks them by leveling up or purchasing with Cost).

Co-op Win Conditions

🏆 Righteous Win: All players reach Maturity L3 and there are no Evil Habituals in play for one full round.

💀 Evil Wins: the Righteous side has not won by the end of round 10.

The clearing round

Reaching L3 is not the win; it starts the clock on it. The moment the last player reaches Maturity L3, a clearing round opens, and it runs from the start of that player's turn until their next turn begins — one full round, every seat getting one turn inside it.

• Clear every Evil Habitual inside that round and the Righteous side wins.
• Still one in play when the round closes and the Righteous side loses — unless round 10 has not finished yet.

That last clause is the whole of it, so it is worth stating on its own: the clearing round never ends before the end of round 10, and it is never shorter than one full round.

• L3 reached in round 9. The clearing round runs to that player's next turn, in round 10. If an Evil Habitual is still standing then, the table keeps going to the end of round 10.
• L3 reached in the middle of round 10. The round is nearly over, but the clearing round still gets its full length — to the beginning of that player's next turn — even though that is past the end of round 10. Nobody loses for reaching L3 late.

Lose L3 during the clearing round, or take a new Evil Habitual, and you are simply not finished: the condition is judged at the end of the round, not the moment it started.

Game modesCo-op: the deck plays Evil · Duel: a person does

Co-op (the original game)

Any number of players on the Righteous team, together against the Evil deck. Nobody plays Evil: the deck runs itself to a fixed set of rules, and the table wins or loses as one.

Solo — one player

The co-op rules, played alone: your Righteous deck against the Evil deck.

Solo plays fine with the many cards that do not involve another player on your team. For a card that does need one — a boost somebody else would pay, an effect aimed at a teammate — pay a Target-Change fee of C1 and read the card as pointing at you. Pay it the ordinary way, by rotating #rot# a card in your Cost Zone.

Raise the fee to C2 or C3 for a harder game.

Duel (experimental)

People on both sides. One or more players run Righteous decks; one or more run Evil decks, choosing which Temptations and Habituals to play and who to play them at. That is the whole difference: in co-op the Evil deck follows fixed rules and cannot think, and in a duel it can. The Righteous side still wins by Maturity; the Evil side wins by grinding Humility (Power) to nothing. Everything in the duel half of this book is the machinery that keeps a played Evil side fair — micro-rewards, micro-boosts, and a Cost Zone sized to how outnumbered each side is.

Playing a Card — the order of things

Every play follows the same five steps, whoever made it and whatever the card is. Boosts are not an exception to this; they are step five.

1. Pay for the card and play it.
2. It may be resisted. The resistance cost on the card — R5, RX — is what answering it takes. Resisted, it never reaches the stack and nothing on it happens.
3. Unresisted, it goes on the stack, ready to resolve.
4. If nothing else is played onto the stack — an instant, a fast card — the card resolves fully: its rules text first, and then its boosts.
5. Boosts, in any order. Whoever is allowed to pay may take any boost on the card, in whatever order they like — the printed order is how they are listed, not a sequence you are held to. Nothing is taken that is not paid for.

A boost goes on the stack like a card

Pay for a boost and its action goes on the stack, exactly as if it had been played as a card of its own. The same window opens: anyone may respond, and a response goes on top.

But a boost action cannot be countered — as the game stands today. A response can do its own work around a boost, and it can change what the boost lands on, but nothing takes a paid boost off the stack.

The boosts belong to the player who played the card, whoever is allowed to pay for them: the glyph says who may pay, never who decides.

The exception is marked on the card

A boost that changes what the card itself is about to do cannot wait until afterwards — by then there is nothing left to change. Those carry the fast mark, a bolt before the boost glyph, and they are taken before the card's own action. Everything else about them, the stack included, is unchanged.

If a card shows no bolt, its boosts are offered after the action. The bolt is the only thing that moves a boost earlier, so a card cannot be ambiguous about its own timing.

The Marks on a Card

Every symbol a card can carry, and what it means. These are the real marks, drawn by the same code that prints the cards — so this list cannot fall out of date with the deck.

Humility (Power) Loss at 0 (Overflow Rule)

If a card causes you to lose Humility (Power) H-1 while already at 0 H0, you must discard 1 card per Humility (Power) lost from your hand or Cost Zone.
