MTG Combo Finder

About the Nerd Leagues MTG Combo Finder

The Nerd Leagues MTG Combo Finder is a free tool that scans any Magic: The Gathering decklist and returns every infinite combo, 2-card combo, extra-turn loop, mass land denial package, and lock combo it contains. It is built on top of the Commander Spellbook combo database, so results stay in sync as new combos are discovered — whether you play Commander, cEDH, Modern, Standard, Pioneer, Legacy, Vintage, or Pauper.

Use it to audit a brew before sleeving up, prove a combo line to your pod, or hunt for finishers you might be just one card away from.

Four ways to find combos

• Paste a decklist — any text format works, including MTGO, MTG Arena exports, Moxfield exports, and plain text. Mark commanders with // Commander for the most accurate Commander Spellbook results.
• Import from Moxfield or Archidekt — paste a deck URL or search a username to browse public decks, then pull the list straight into the Combo Finder.
• Select a saved deck — sign in and pick any deck from your Nerd Leagues Deck Builder to analyze it instantly.
• Search by card — type a single card name (like Basalt Monolith or Thassa's Oracle) and see every known combo that uses it. Great for brewing around a specific piece.

What the Combo Finder shows you

• In Your Deck — every combo your decklist already completes.
• 1 Card Away — combos you would unlock by adding a single missing piece, with the missing card called out.
• Bracket filters — filter by Commander Spellbook bracket: Ruthless, Spicy, Powerful, Core, Oddball, Exhibition, and Banned.
• Combo type tags — two-card combos, infinite combos, extra turns, mass land denial, lock combos, and opponent-control combos.
• Add combos and missing cards to your decks — if you're signed in, send any 1-card-away missing card straight into a deck in your Nerd Leagues Deck Builder with a single click, or, from the search-by-card results, add an entire combo to one of your decks at once.
