DeckCortex — Master the Meta. Powered by AI.
DeckCortex is an AI-powered Magic: The Gathering deck workbench. Run 16 simulations on your exact list — power level, kill clock, mana consistency — then get AI reports that explain what to change and why. Free to start, with one-click import from Moxfield.
Everything you need to tune a deck with data
- See your deck's real power level — 16 client-side simulations score your exact list — power level, goldfish kill clock, mana consistency, resilience and more. Stop guessing whether it's actually good.
- AI reports that explain the numbers — From quick primers to full deck analyses, mana audits and coaching, AI turns every simulation into readable strategy — game plan, weak spots, what to change.
- The tournament meta, built in — Fresh staples, inclusion rates and top-performing decks from real tournament results sit right next to your list, so you build against what's actually winning.
Supported formats include Commander / EDH, cEDH and Duel Commander, plus Standard, Pioneer, Modern, Legacy, Vintage, Pauper and Premodern, and the Arena formats Historic, Timeless and Alchemy. Card data comes from Scryfall; meta and card popularity from EDHREC, MTGTop8 and Moxfield; combo detection from Commander Spellbook.
