MTG Combo Finder - a free Commander and EDH combo finder. Paste your decklist to instantly find every combo in your deck, what each one does (including infinite combos and game-winning loops), and the combos you are one card away from. Powered by the Commander Spellbook database.
How to Find Combos in Your Deck
Simply paste your entire decklist, including your commander or your sideboard, and click “Find Combos.” The calculator will then automatically parse your decklist and do two things. First, it'll detect all combos in your deck, their outcomes, execution instructions, and how many other decks online run those same combos.
Then, it'll figure out what combos you're just one card away from. For example, if you already have Kelpie Guide in your deck, then adding Freed from the Real will immediately set you up with an infinite mana combo.
How Does it Work?
Our calculator automatically parses out your decklist into a list of individual cards and then does a few things. First, it asks Scryfall for information about each card like the image, it's function, mana cost, etc. Then, it references our own database + Commander Spellbook for combos actively in your deck. Finally, it looks at what infinite combos you're just a single card away from including in your deck, taking into account legality and your deck's colors.
