MTG deck analyzer for Commander, with AI

Updated 2026-11-11

Paste a Commander decklist below for its mana curve, colours, land count, opening-hand odds and bracket, free and with no account. Then Grover, the AI deck assistant, answers what to cut and what to upgrade against your actual list.

Free Commander deck analyzer: paste a list

Paste a Commander decklist in any common text or CSV export format. You get its mana curve, colours, card types, land count, average mana value, opening-hand odds and bracket, with no account and no AI: every reading is a fixed calculation, so it uses no Grover message.

Card names must be in English for now. A line we cannot match is listed with the bracket as unrecognized and left out of every reading.

What the deck analysis covers

Open a deck and five readings sit side by side; only the first one uses a Grover message:

Ask AI: Grover reads your actual list and answers what to cut, what to upgrade and whether the mana base holds up;
Analysis: the mana curve, the colour distribution, the average mana value, the land count and the card types;
Playtest: an opening-hand simulation with the average number of lands in an opening hand, the share of keepable hands and the lands you can expect by each turn;
Bracket: for a Commander deck, the deck builder counts your Game Changers and shows your list's bracket as you build;
Validation: every legality problem with the card behind it, such as a card outside your commander's colour identity, a banned card, a second copy or the wrong deck size.

How to analyze a Commander deck in three steps

From a decklist to a short list of cuts:

Import. Paste your decklist or upload a file, or build the deck card by card. A free account saves the deck.
Read. Open the Analysis and Validation tabs for the curve, the colours and anything that is not legal, and check the deck's bracket.
Ask. Open the Ask AI tab and ask Grover your question. The deck is attached to the conversation, so the answer names cards from your list.

MTG AI deck analyzer: what to ask Grover

Ask in plain language in the deck's Ask AI tab. Five questions it is made for:

"This is at 104 cards. What do I cut to get to 100, and why?"
"Which three cards would you replace first, and with what?"
"Does my mana base hold up for three colours?"
"Do I have enough ramp and card draw for this curve?"
"Which cards don't fit what my commander does?"

Grover explains its reasons and you decide what changes. A rules answer is a starting point: check it against the Comprehensive Rules.

EDH deck optimizer: lower or raise the bracket

To move a deck to another bracket, start from what sets it. For a Commander deck, the deck builder shows the bracket and why: the number of Game Changers, and any mass land denial, extra-turn cards or two-card combos. Then ask Grover, for example "Take this deck to Bracket 2: what do I swap out?", and check the new list's bracket the same way.

No account? Check a pasted list's bracket

The free bracket checker reads any pasted Commander decklist with no account and no AI: it shows the lowest bracket its cards point to, from 2 to 4, the cards behind it and what would move the list to another bracket. It does not use a Grover message.

Free plan and allowances

Every plan includes the full deck builder, so the Analysis, Validation and Playtest tabs and the bracket are free and unlimited. Each question to Grover uses one message from your monthly allowance; the Free plan includes 20 a month. Prices for your country are on the pricing page.

Questions about the deck analyzer

Is there a free MTG deck analyzer?

Yes. Paste a list at the top of this page for the curve, colours, lands, opening-hand odds and bracket, with no account. On the Free plan the deck builder's readings cost nothing either, and 20 Grover messages a month cover questions about cuts and upgrades.

Will it tell me which cards to cut?

Yes. Ask Grover in the deck's Ask AI tab, such as "What do I cut to get to 100, and why?": the deck is attached to the conversation, so it names cards from your list and says why.

Can it rate my deck?

Not with a score out of ten. For a Commander deck, Mana Grove reads the bracket instead: the lowest bracket its cards point to, 2 to 4, and what puts it there, on the deck page and in the free bracket checker.

What is the difference between the analyzer and the deck builder?

They are one app. The deck builder is where you build and edit a deck; the analysis is the readings beside it and Grover's answers about your list. To draft a new deck from a description instead, there is Grover, the MTG AI deck builder for Commander.
