deck-tuner
Deck Tuner
Analyze and optimize existing 60-card constructed decks with sideboards for competitive MTG formats. Covers mainboard card evaluation, mana base tuning, sideboard planning against the metagame, and budget-aware upgrade paths.
The Iron Rule
Never assume what a card does. Always look up oracle text via scryfall-lookup before evaluating a card. Training data may be outdated, cards get errata, and memory conflates similar effects.
Progress Tracking
Create these top-level todos at session start. Mark in_progress immediately when starting a step, completed immediately when finishing. Never batch updates.
- Step 1: Parse Deck List
- Step 2: Hydrate Card Data
- Step 2.5: Baseline Metrics
- Step 3: User Intake
- Step 4: Research
