+# Deck Builder Design
+
+## Overview
+Semi-automated tool to build Commander decks from existing card collections.
+
+## Architecture
+- Script: `scripts/build_deck.py`
+- Input: Hydrated collection JSON (`output/hydrated/deck.json`)
+- Output: Deck JSON file in `data/decks/`
+
+## Components
+
+### 1. Collection Analyzer
+- Analyzes color distribution across collection
+- Identifies card type distribution (creatures, spells, lands)
+- Calculates CMC distribution
+- Finds potential synergies (keywords, creature types)
+
+### 2. Commander Suggester
+- Identifies legendary creatures and planeswalkers in collection
+- Scores commanders based on:
+  - Color support in collection
+  - Number of cards matching color identity
+  - Synergistic mechanics present
+- Provides top 3-5 commander recommendations
+
+### 3. Deck Generator
+- Creates starter decklist based on chosen commander
+- Includes:
+  - Commander (1 card)
+  - Lands (35-40 cards matching color identity)
+  - Creatures, spells, and artifacts matching color identity
+  - Balanced mana curve
+- Ensures deck meets Commander format requirements
+
+### 4. Refinement Tools
+- Functions to add/remove specific cards
+- Balance mana curve
+- Adjust land count
+- Filter by card type or CMC
+
+## Data Flow
+
+1. Load hydrated collection from `output/hydrated/deck.json`
+2. Analyze collection statistics
+3. Identify potential commanders
+4. User selects commander
+5. Generate starter decklist
+6. Save deck JSON file
+7. Provide analysis report
+
+## Error Handling
+
+- Validate input file exists and is properly formatted
+- Handle cases where no suitable commanders are found
+- Provide fallback options for incomplete collections
+- Validate generated deck meets format requirements
+
+## Testing Strategy
+
+1. Test with existing collection files
+2. Verify generated decks meet Commander format requirements
+3. Check color identity matching works correctly
+4. Validate mana curve balancing
+5. Test edge cases (small collections, mono-color, multi-color)
+
+## Usage Documentation
+
+Add to README.md:
+
+```markdown
+### Build a Deck From Your Collection
+
+```bash
+# Analyze your collection and build a deck
+python scripts/build_deck.py --collection output/hydrated/deck.json --name my_new_deck
+
+# View suggested commanders
+python scripts/build_deck.py --collection output/hydrated/deck.json --list-commanders
+
+# Build deck with specific commander
+python scripts/build_deck.py --collection output/hydrated/deck.json --name my_deck --commander "Choco, Seeker of Paradise"
+```
+
+The script will:
+1. Analyze your collection for color distribution and card types
+2. Suggest potential commanders from your collection
+3. Generate a starter decklist matching the commander's color identity
+4. Save the deck to `data/decks/<name>.json`
+5. Provide a summary report with suggestions for improvements
+
+After building, you can:
+- Manually edit the deck file
+- Run analysis to find upgrades: `python scripts/analyze_decks.py --collection output/hydrated/deck.json --deck-dir data/decks/`
+- Generate a report: `python scripts/deck_report.py --collection output/hydrated/deck.json --decks-dir data/decks/`
+```
+
+## Implementation Plan
+
+1. Create `scripts/build_deck.py` with argparse CLI
+2. Implement collection analysis functions
+3. Build commander suggestion algorithm
+4. Create deck generation logic
+5. Add refinement tools
+6. Write comprehensive tests
+7. Update README documentation
+8. Add to pre-commit hook for auto-docs

+# Deck Builder Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Build a semi-automated deck builder that creates Commander decks from existing card collections
+
+**Architecture:** Python script that analyzes collection data, suggests commanders, and generates starter decklists
+
+**Tech Stack:** Python 3 standard library (argparse, json, collections)
+
+---
+
+### Task 1: Create Deck Builder Script
+
+**Files:**
+- Create: `scripts/build_deck.py`
+
+**Step 1: Write script skeleton with CLI interface**

+```
+
+**Step 2: Test basic functionality**
+
+Run: `python scripts/build_deck.py --help`
+Expected: Help message with all arguments
+
+**Step 3: Test with existing collection**
+
+Run: `python scripts/build_deck.py --collection output/hydrated/deck.json --list-commanders`
+Expected: List of potential commanders from collection
+
+**Step 4: Generate a test deck**
+
+Run: `python scripts/build_deck.py --collection output/hydrated/deck.json --name test_deck`
+Expected: Deck file created in data/decks/
+
+**Step 5: Commit initial implementation**
+
+```bash
+git add scripts/build_deck.py
+git commit -m "feat: add deck builder script"
+```
+
+---
+
+### Task 2: Add Documentation to README
+
+**Files:**
+- Modify: `README.md` (add usage section)
+
+**Step 1: Add deck builder usage to README**
+
+Add to README.md after the "Find Synergies" section:
+
+```markdown
+### Build a Deck From Your Collection
+
+```bash
+# List suggested commanders from your collection
+python scripts/build_deck.py --collection output/hydrated/deck.json --list-commanders
+
+# Build deck with suggested commander
+python scripts/build_deck.py --collection output/hydrated/deck.json --name my_new_deck
+
+# Build deck with specific commander
+python scripts/build_deck.py --collection output/hydrated/deck.json --name my_deck --commander "Choco, Seeker of Paradise"
+```
+
+The deck builder will:
+1. Analyze your collection for color distribution and card types
+2. Suggest potential commanders from your collection
+3. Generate a starter decklist matching the commander's color identity
+4. Save the deck to `data/decks/<name>.json`
+5. Provide a summary report
+
+After building, refine your deck:
+- Edit the deck file manually
+- Find upgrades: `python scripts/analyze_decks.py --collection output/hydrated/deck.json --deck-dir data/decks/`
+- Generate reports: `python scripts/deck_report.py --collection output/hydrated/deck.json --decks-dir data/decks/`
+```
+
+**Step 2: Update README**
+
+Run: Edit README.md to add the new section
+
+**Step 3: Commit documentation**
+
+```bash
+git add README.md
+git commit -m "docs: add deck builder usage to README"
+```
+
+---
+
+### Task 3: Enhance Deck Generation Logic
+
+**Files:**
+- Modify: `scripts/build_deck.py` (improve generate_deck function)
+
+**Step 1: Improve land selection**
+
+Update generate_deck to better handle land selection:
+- Prioritize basic lands
+- Include color-fixing lands when available
+- Balance land types for multi-color decks
+
+**Step 2: Add mana curve balancing**
+
+Add function to balance mana curve:
+- Target distribution: 10-12 cards at 2 CMC, 8-10 at 3, 6-8 at 4, etc.
+- Adjust card selection to match curve
+
+**Step 3: Test enhanced generation**
+
+Run: `python scripts/build_deck.py --collection output/hydrated/deck.json --name enhanced_deck`
+Expected: Better balanced deck with improved mana curve
+
+**Step 4: Commit improvements**
+
+```bash
+git add scripts/build_deck.py
+git commit -m "feat: improve deck generation logic"
+```
+
+---
+
+### Task 4: Add Testing and Validation
+
+**Files:**
+- Create: `tests/test_build_deck.py`
+
+**Step 1: Write unit tests**
+
+```python
+import json
+import tempfile

+    
+    commanders = find_commanders(test_cards)
+    assert len(commanders) == 1
+    assert commanders[0]['name'] == "Legendary Creature"
+```
+
+**Step 2: Run tests**
+
+Run: `python -m pytest tests/test_build_deck.py -v`
+Expected: All tests pass
+
+**Step 3: Commit tests**
+
+```bash
+git add tests/test_build_deck.py
+git commit -m "test: add unit tests for deck builder"
+```
+
+---
+
+### Task 5: Final Integration and Testing
+
+**Files:**
+- Modify: `scripts/update_docs.py` (add deck builder to auto-docs)
+
+**Step 1: Update documentation generator**
+
+Add deck builder to the auto-generated documentation
+
+**Step 2: Test complete workflow**
+
+```bash
+# Test complete workflow
+python hydrate.py hydrate data/collection/Box1\ 2026-01-30.txt -o output/hydrated/ -c cache/card_cache.json
+python scripts/build_deck.py --collection output/hydrated/deck.json --list-commanders
+python scripts/build_deck.py --collection output/hydrated/deck.json --name my_test_deck
+python scripts/analyze_decks.py --collection output/hydrated/deck.json --deck-dir data/decks/
+```
+
+**Step 3: Verify all tests pass**
+
+Run: `python -m pytest tests/ -v`
+Expected: All tests pass
+
+**Step 4: Final commit**
+
+```bash
+git add .
+git commit -m "feat: complete deck builder implementation"
+```
+
+---
+
+## Plan Complete
+
+**Execution Options:**
+
+1. **Subagent-Driven (this session)** - I'll implement task-by-task with your review
+2. **Parallel Session** - You can run this plan in a separate session
+
+Which approach would you prefer?
