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 Training data may be outdated, cards get errata, and memory conflates similar effects.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.
