MTG Commander Deck Analyzer - Decode the secrets of your Commander deck

Tome - MTG Commander Deck Analyzer

Tome is a Python CLI tool that analyzes Commander decklists against best practices, combining rule-based heuristics validation with LLM-powered strategic analysis using the Scryfall API for card data and Claude API for intelligent recommendations.

Features

Deck Analysis

• Decklist Parsing: Supports multiple common formats (Moxfield, MTGO, simple text)
• Moxfield URL Support: Analyze decks directly from Moxfield URLs
• Flexible Deck Size: Analyze incomplete (<100) or oversized (>100) decks with suggestions
• Scryfall Integration: Automatic card data retrieval with 30-day local caching

Heuristic Validation

Checks your deck against established Commander best practices:

• Land count and mana base analysis
• Ramp spells (8-10 recommended)
• Card draw (10+ recommended)
• Removal and board wipes
• Instant-speed interaction
• Graveyard hate
• Color fixing analysis per color

Budget Analysis

• Total deck cost calculation
• Identifies expensive cards (>10% of budget)
• Budget category classification (Ultra-Budget to No-Budget)

LLM Strategic Analysis

• Claude-powered insights on theme, synergies, and improvements
• Interactive chat mode for follow-up questions
• Context-aware recommendations based on your deck's strengths and weaknesses

Interactive Deck Modification

• Add cards: add Sol Ring or add Rhystic Study x2
• Remove cards: remove Temple of the False God
• Swap cards: swap Diabolic Tutor for Demonic Tutor
• Batch add/remove: paste multiple card names at once
• Export updated decklist in Moxfield-compatible format

Collection Comparison

• Compare your deck against your existing card collection
• AI-powered swap suggestions that understand card synergies
• Find budget savings: cards you own that could replace expensive cards
• Find upgrades: better cards you already have
• Interactive swap acceptance: accept 1 or accept all budget

Collection Comparison

Compare your deck against cards you already own:

tome analyze my_deck.txt --collection my_collection.txt

The collection file uses the same format as deck files. Tome will suggest:

• Budget swaps: expensive cards that can be replaced with cheaper cards you own
• Upgrades: better cards you already have

Interactive Commands

After analysis, you enter interactive mode:

> add Sol Ring              # Add a card
> remove Island             # Remove a card
> swap Card A for Card B    # Swap cards
> show swaps                # Show collection swap suggestions
> accept 1                  # Accept swap suggestion #1
> accept all budget         # Accept all high-confidence budget swaps
> summary                   # Show modifications made
> export                    # Export updated decklist
> quit                      # Exit

You can also ask questions about your deck:

> What cards should I cut for more draw?
> Is this deck too slow?
> Should I add more ramp or cut lands?
