Use for a deckbuilder, TCG/CCG, or roguelike deckbuilder.\n---\n\n# Card Game\n\nA playbook for card games — card data, the deck/hand/discard zones, the turn structure, and\nhow card effects resolve. This is a **compositional** skill: it models cards as data and wires\nthem to UI. It does not re-teach data assets or UI nodes; it defines the zone model, the draw\nmachinery, and the effect-resolution rules that keep a card game correct and bug-free.\n\n## When to use\n\n- Use when building any game where the core objects are **cards** moving between zones\n  (deck → hand → play → discard): deckbuilder, TCG/CCG, solitaire, roguelike deckbuilder.\n- Use when designing draw/shuffle/reshuffle, turn structure, card costs, or how effects resolve.\n\n**When *not* to use:** board/tile state with matching rules → `puzzle`. RPG with an\nincidental card battler → start from `rpg`. For defining cards as assets, use `godot-resources`\n/ `unity-scriptableobjects`; for the hand/drag UI, use `godot-ui-control`.\n\n## Core loop\n\n**Draw to your hand → spend resources to play cards → effects resolve and change the board →\nend the turn (cleanup/discard) → opponent/next phase → repeat until a win condition.** Depth\ncomes from the *combinations* a hand allows; the engine's job is to resolve them unambiguously.\n\n## Must-have systems\n\n1. **Card data** — id, name, cost, type, text, and an effect spec (data, not code).\n2. **Zones** — deck (draw pile), hand, play/board, discard, exile/removed; cards live in exactly one.\n3. **Draw + shuffle + reshuffle** — draw from deck to hand; reshuffle discard into deck when empty.\n4. **Turn structure** — phases (untap/draw/main/combat/end) as a state machine.\n5. **Resource system** — mana/energy/actions that gate how much you do per turn.\n6. **Effect resolution** — apply a card's effects in a defined order; handle targets and triggers.\n7. **Win/loss condition** — life total, deck-out, objective.\n8. **UI** — hand layout, drag/drop or tap-to-play, zone counts, targeting affordances.\n\n## Design knobs\n\n| Knob | Effect | Notes |\n|------|--------|-------|\n| Starting hand / draw-per-turn | tempo, consistency | More draw = less variance. |\n| Hand size limit | hoarding vs. use | Discard down at end of turn. |\n| Deck size (min) | consistency | Smaller = more reliable combos. |\n| Resource curve | what's playable when | \"Mana curve\" paces power. |\n| Card rarity / power budget | balance | Stronger cards cost more / are rarer. |\n| Determinism vs. randomness | skill vs. swing | Shuffle + random effects add variance. |\n| Reshuffle rules | deck-out, fatigue | Reshuffle discard, or punish empty deck. |\n| Removal / answers | counterplay | Every threat needs an answer in the pool. |\n\n## Patterns\n\n### 1. Zones + draw with automatic reshuffle\n\n```python\n# Pseudocode. A card is in exactly one zone at a time; moving = remove here, add there.\ndef draw(n):\n    for _ in range(n):\n        if not deck:\n            if not discard:          # truly empty: deck-out (lose, or take fatigue)\n                on_deck_out(); return\n            deck.extend(discard)     # reshuffle discard into deck\n            discard.clear()\n            shuffle(deck, rng)       # use a seeded RNG (see save-systems for replays)\n        hand.append(deck.pop())\n```\n\n### 2. Card as data + effect resolution\n\n```python\n# Pseudocode. Effects are a data list interpreted by the engine — not bespoke code per card.\ncard = {\n    \"id\": \"fireball\", \"cost\": 3, \"type\": \"spell\",\n    \"effects\": [ {\"op\": \"damage\", \"amount\": 6, \"target\": \"chosen_enemy\"} ],\n}\ndef play(card, caster):\n    if resources[caster] < card.cost: return False     # can't afford\n    resources[caster] -= card.cost\n    move(card, from_zone=hand, to_zone=play_or_discard(card))\n    for fx in card.effects:\n        resolve_effect(fx, caster)                      # one interpreter handles every card\n    return True\n```\n\n### 3. Turn structure as a phase machine\n\n```python\n# Pseudocode. Fixed phases keep timing windows (triggers, priority) unambiguous.\nPHASES = [\"untap\", \"draw\", \"main\", \"combat\", \"end\"]\ndef take_turn(player):\n    for phase in PHASES:\n        enter_phase(player, phase)        # fire \"on_phase\" triggers here\n        if phase == \"draw\":   draw(1)\n        if phase == \"main\":   await player_plays_cards()\n        if phase == \"combat\": resolve_combat()\n        if phase == \"end\":    discard_to_hand_limit(player); clear_temporary_effects()\n```\n\n## Pitfalls / failure modes\n\n- **A card existing in two zones at once** → duplication/loss bugs. Enforce \"exactly one zone\";\n  move = remove-then-add, and assert no card appears twice.\n- **Forgetting to reshuffle** → draws silently fail or crash on empty deck. Reshuffle discard,\n  or define deck-out/fatigue explicitly (Pattern 1).\n- **One function per card** → unmaintainable and untestable. Make effects **data** interpreted\n  by a small set of operations (Pattern 2).\n- **Ambiguous effect order / simultaneous triggers** → nondeterministic outcomes. Resolve in a\n  defined order (a queue or stack); document LIFO vs. FIFO (refs).\n- **Unseeded shuffle in a game that needs replays/undo** → can't reproduce. Use a seeded RNG.\n- **No hand limit / no answers** → degenerate hoarding or unbeatable threats. Add a hand cap and\n  ensure removal exists for every threat archetype.\n- **Targeting state leaks** → a cancelled play leaves the board mid-targeting. Make play\n  atomic: validate cost + targets first, then commit.\n\n## Composition (build it from these skills)\n\n- **Card content:** `godot-resources` / `unity-scriptableobjects` — define each card as a data asset.\n- **UI:** `game-ui-ux` for layout, scaling, and focus navigation; `godot-ui-control` for hand layout, drag/drop, zone counts, and targeting prompts.\n- **Persistence/replays:** `save-systems` for collection, run state (roguelike deckbuilder), and seeded replays.\n- **Opponent AI:** `game-ai` for an AI that evaluates playable cards and picks targets.\n- **Animation/feedback:** the engine animation skill for card movement; `audio-design` for cues.\n- **Scripting:** `godot-gdscript` / `unity-csharp-scripting` for the effect interpreter.\n\n## References\n\n- For the effect queue/stack, keywords/triggers, targeting, deckbuilder vs. constructed\n  archetypes, and shuffle fairness, read `references/effect-resolution.md`.\n","tagline":"Build a card game: card data, deck/hand/discard zones, draw/shuffle/reshuffle, a turn structure, costs, and effect resolution.
