What the Deck Analyzer Checks

A full diagnosis of your list, card by card, backed by real Scryfall data

Cards to Cut

The weak links get flagged - underperformers, win-more cards, do-nothing pet cards, and anything pulling against your strategy. Every cut comes with a reason, so you decide with context instead of guesswork.

High-Impact Adds

Get specific upgrades that raise your deck's consistency and ceiling, ranked by how much they actually move the needle - not by how popular they are on a top-100 list.

Mana Curve & Ramp

A top-heavy curve, too few early plays, or thin ramp all get spotted, with fixes measured against healthy ratios for your format and strategy.

Synergy & Combo Gaps

He searches across 40,000+ cards for interactions your list is missing and points out where your deck lacks a coherent game plan or a payoff for the pieces you already run.

Missing Staples

Your list is checked against the removal, card-draw, and ramp packages an archetype expects, so you stop leaving format staples and obvious includes on the bench.

Power-Level Tuning

He reads the deck's bracket and helps you push it up toward cEDH or dial it down for a casual table - swapping fast mana, tutors, and combos in or out to match the pod you play in.

Checked, not guessed

Every card clears a deterministic legality gate before it can be proposed

Every card is checked against the deck's format before it can be proposed. Not by the language model deciding a card looks right — by deterministic code that runs first, on the real card, against the format's rules. A card that would break them never reaches you as a proposal.

And nothing is written to your deck by an agent. Every add, every removal and every rename arrives as a proposal you accept or decline.

How the Deck Analyzer Works

From a finished list to a clear upgrade plan in minutes

Paste or Upload Your Decklist

Drop in any list - plain text, a commander plus a pile of cards, or an export copied from a deck site. Quantities like "2x Counterspell" are understood, and every line is matched to a real card with accurate Scryfall data.

Carl Analyzes It

Carl, the deck-building agent, grades the whole deck: weak cards, curve and ramp balance, mana base, missing staples, synergy gaps, and overall power level. Each note comes with the reasoning behind it, so the analysis teaches you as it goes.

Apply the Upgrades

Chat back and forth to lock in cuts and adds, ask for budget swaps, or push the power level. "Cut the weakest five," "lower my curve," "make it Bracket 3" - the list is re-optimized in real time, with each change explained.

Why Use an AI Deck Optimizer

A focused second opinion on the exact 99 you already play

Specific to Your List

Every cut and add is judged against the exact cards in your deck - not an averaged "most-played" list that ignores how your build actually works. The advice fits your deck, not a statistical stranger's.

Catches What You Miss

After weeks of staring at the same 99, you stop seeing the dead cards and curve problems. This is an objective second read that surfaces the weak spots you've gone blind to.

Clear Upgrade Path

Instead of a vague "get better cards," you get a prioritized list ranked by impact, so you spend your budget where it actually changes games.

Iterate by Conversation

Refine the analysis the way you can't with a static checker. Change a constraint, ask for cheaper options, or chase a different win condition and the list is re-graded on the spot.

Optimize a Commander Deck

Your 100-card list, measured against the ratios a healthy Commander deck wants

Quick Deck Formula (100 cards)

• 1 Commander

• 36-38 Lands

• 10-12 Ramp

• 8-10 Card Draw

• 8-10 Removal

• 7-10 Win Conditions

• 15-20 Synergy/Theme Cards

• 3-5 Flex Slots

A Worked Example

Paste a 38-land Gruul deck with 6 ramp, 5 draw, and a 4.1 average mana value and the read is concrete: the curve is too high and the deck will stall.

He suggests: trim to 36 lands, add 4-5 ramp pieces (Sol Ring, Rampant Growth, a signet), add 3-4 repeatable draw sources, and cut the three highest-cost cards that don't close the game. Result: a smoother deck that casts its commander on time.

Legality & Color Identity

Your commander's color identity is read first, so anything off-color or on the Commander ban list is flagged; then ramp, card-draw, and interaction counts are checked against healthy EDH targets, with adds recommended wherever a package is running thin.

Frequently Asked Questions

Is the MTG deck analyzer free?

Yes. You can paste your decklist and get a full analysis for free, with no credit card required. Create an account if you want to save the optimized deck and track your changes over time.

How do I analyze my deck with the AI?

Open the chat, paste or upload your decklist, and ask for an analysis. Every card is read against real Scryfall data, and you get back specific cuts, adds, curve fixes, and synergy notes - each with a reason.

Can it optimize a Commander / EDH deck?

Yes - Commander is the most common use. Your 100-card list is checked for color-identity legality, mana base, ramp, draw and removal balance, missing staples, and synergy gaps, and you get prioritized upgrades.

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

The deck builder creates a brand-new decklist from a commander or strategy you describe. The analyzer takes a deck you already have and optimizes it. Use the AI Deck Builder to start from scratch, the analyzer to improve what you play.

Will the analyzer tell me which cards to cut?

Yes. Underperformers, win-more cards, and anything that does not fit your strategy get flagged, each with the reason it is a candidate to cut, so you make the final call with context.

Can it help raise or lower my deck's power level?

Yes. Name the bracket or table you are aiming for and the list is tuned up toward cEDH or down for casual play, swapping cards to match the power level you want.

What decklist formats can I paste in?

Plain text lists, a commander plus a card list, and common exports from deck-building sites all work. Each line is matched to a real card before the deck is analyzed.

Does it suggest budget upgrades?

Yes. Set a total or per-card budget and you get the highest-impact affordable upgrades, or swaps for the expensive cards in your existing list that keep the deck's plan intact.
