DeckStir combines AI analysis, real EDHREC community data, and intuitive tools to help you build, analyze, and optimize Commander decks at every skill level and budget.
AI-Powered Analysis Engine
DeckStir uses a multi-phase AI pipeline built on GPT-4 class models to analyze every card in your Commander deck. Cards are categorized by function (ramp, removal, draw, threats, combo pieces), then cross-referenced with EDHREC community data to score synergies and identify optimization opportunities.
Get a calibrated 1–10 power level rating mapped to the official Commander Format Panel 5-bracket system: Exhibition, Core, Upgraded, Optimized, and cEDH. Scored across four performance axes — Speed, Consistency, Resilience, and Draw Engine — with a radar chart that visualizes your deck's strengths at a glance.
From synergy scoring to deck building, every tool is designed to make you a better Commander player.
EDHREC Synergy Scoring
Every card in your deck is scored for synergy with your commander and the rest of your 99. High-synergy staples and hidden gems are highlighted. Low-synergy cards are flagged as potential cuts.
Mana Base Optimization
Color pip analysis, mana curve visualization, land-count recommendations, ramp evaluation, and color-fixing assessment. Identifies mana screw and flood risks before they happen in-game.
Budget Upgrade Paths
Upgrade suggestions at multiple budget tiers — from sub-dollar swaps to impactful staples. Each recommendation includes reasoning so you can make informed choices.
Legality & Ban List Checks
Automatic detection of banned cards, color identity violations, duplicate entries, and illegal sideboard configurations. Updated with the latest Commander Rules Committee announcements.
Follow-Up AI Chat
After your analysis, ask the AI follow-up questions like "How can I improve my removal suite?" or "What combos can I add under $20?" Responses are context-aware and reference your actual decklist.
Deck Building Assistant
Build complete Commander decks from scratch. Choose a commander, set constraints (budget, power level, theme), and let the AI suggest a full 100-card list with lands, ramp, draw, and win conditions.
Shareable Analysis Reports
Every analysis generates a unique shareable link. Send it to playgroup members, post it in Discord, or embed it in forum discussions. No account required to view shared reports.
Analysis History & Tracking
All your analyses are saved automatically. Compare deck versions side-by-side, track power level changes over time, and see exactly what impact each upgrade had.
