The fastest way to know your deck's power level
Every Commander game starts with the same question: how strong is this deck? Leyline's free Commander power level calculator answers it in seconds. Paste a decklist — no account, no friction — and our deck analyzer reads all 100 cards, detects infinite combos, evaluates your mana base, and returns a clear power score plus a Commander bracket rating from 1 to 5.
Instead of guessing where your EDH deck lands on the power level scale, you get hard numbers: a power rating, a bracket, salt and fear scores that describe how the deck actually feels to play against, and per-card impact scores that show which cards carry your build. It's the deck power level checker built for honest Rule 0 conversations and perfectly matched pods.
Instant power score
A single, easy-to-read number that tells you how strong your Commander deck is — calculated in seconds from the full decklist.
Commander bracket (1–5)
Automatic bracket rating that maps to the official Commander bracket system, so Rule 0 conversations start with real data.
Combo detection
Surfaces infinite and game-ending combos in your list — and the exact cards that enable them — so nothing hides in your 99.
Mana base analysis
Checks color requirements, sources, and fixing against your curve to flag a shaky mana base before it costs you a game.
Salt & Fear ratings
Goes beyond raw power to estimate how oppressive and threatening your deck feels to play against at a real table.
Per-card impact scores
Every card is scored for its contribution so you can spot dead weight and the cards quietly carrying your deck.
Paste. Scan. Know.

A deck score that reflects how the game actually plays
A single power number never tells the whole story. Two decks can share a power level and feel completely different across the table. That's why Leyline scores every Commander deck on four dimensions instead of one — so you understand not just how strong a deck is, but how it plays.
Power captures raw strength, speed, and consistency. Salt estimates how frustrating your strategy is to face — think stax, land destruction, and mass bounce. Fear measures threat density and table pressure. Airtime reflects how interactive and grindy your games tend to run. Together they turn a vague vibe check into a precise, shareable profile of your deck.
Built for the Commander bracket system and Rule 0
Wizards' Commander bracket system gives playgroups a shared 1 to 5 vocabulary for deck strength — from precon-level casual all the way up to cEDH. Leyline maps your decklist to a bracket automatically, so your Rule 0 conversation starts from real data instead of optimistic memory.
Building to a target bracket? Scan, tweak, and rescan until your EDH deck lands exactly where you want it. Hosting a pod night? Have everyone run their list through the power level calculator first so the table is balanced before the first land hits the battlefield.
Commander power level, answered
How does the Commander power level calculator work?
Paste or import a decklist and Leyline analyzes every card in seconds. It scores your deck across four axes — Power, Salt, Fear, and Airtime — detects two- and three-card infinite combos, evaluates your mana base and color identity, and rolls everything up into a power rating and a Commander bracket (1–5). The whole analysis runs instantly and is completely free.
Do I need an account to check my deck power level?
No. The deck scanner is free and requires no signup. Paste a decklist or import from Archidekt and you get a full power breakdown right away. Creating a free account just lets you save decks, track versions over time, and revisit past analyses.
What is the Commander bracket system?
The Commander bracket system is a 1–5 scale (from precon-level casual up to cEDH) that helps playgroups agree on deck strength before a game — the heart of a good “Rule 0” conversation. Leyline maps your decklist to a bracket automatically so you can find balanced pods and avoid mismatched games.
What do Power, Salt, Fear, and Airtime mean?
Power measures raw deck strength and speed. Salt estimates how frustrating your strategy feels to play against (stax, land destruction, mass bounce). Fear captures threat density and how much pressure your board applies. Airtime reflects how interactive and grindy your games tend to run. Together they describe not just how strong a deck is, but how it actually plays at the table.
Can it detect infinite combos in my deck?
Yes. The analyzer flags known infinite and game-winning combos — including the specific cards that complete them — so you can see your win conditions at a glance and decide whether they fit the bracket you are aiming for.
Is the power level calculator accurate for cEDH?
It scores the full spectrum from casual battlecruiser decks to cEDH. High-powered lists surface fast mana, efficient tutors, compact combos, and dense interaction, which push the power score and bracket toward the top of the scale.
