ArcMind — MTG Commander Analyzer, Power Level & Bracket Calculator
ArcMind is a free, instant power level analyzer for Magic: The Gathering Commander (EDH)
decks. Paste your decklist and receive a 0–10 score across five axes that reflect every
dimension of deck strength, from how fast you can execute your game plan to how well you
can survive disruption.
Five-Axis Scoring System
Every Commander deck is evaluated across five dimensions, each scored 0–10:
-
Speed (15%) — How quickly the deck can threaten a win. Measures ramp
density, average CMC, commander casting cost, and early combo presence. Cheap cards (CMC
0–2) are weighted more heavily via a CMC quality multiplier.
-
Consistency (30%) — How reliably the deck finds and executes its game
plan. Values draw engines, tutors, mana base color-fixing, EDHREC synergy density, and
the presence of finisher cards. The highest-weighted axis.
-
Interaction (20%) — The deck's ability to disrupt opponents. Scores
targeted removal, board wipes, counterspells, graveyard hate, and stax effects. Rewards
diverse answer types and low-CMC interaction.
-
Resilience (15%) — How well the deck recovers from disruption. Values
protection spells, recursion engines, and counterspells. Commanders with built-in
recursion or protection receive a bonus from the command zone.
-
Efficiency (20%) — How much value the deck generates per mana. Scores
land quality (untapped, fetch lands), non-land ramp density, mana curve shape, and cost
reduction effects.
Bracket Classification (1–5)
After scoring, every deck is classified into one of five brackets aligned with the
Commander Rules Committee guidelines: Exhibition (1), Core (2), Upgraded (3), Optimized
(4), and cEDH (5). Bracket assignment checks for rule violations including mass land
denial, extra turn cards, 2-card infinite combos, and game changer cards.
Combo Detection
ArcMind queries the Commander Spellbook database to detect known infinite combos and
near-miss combos (combos where you are missing one piece). Combos are displayed with the
full card list and result description.
Card-by-Card Breakdown
Every card in your deck is classified by role — ramp, tutor, removal, counterspell,
wincon, combo piece, and 38 others — and assigned an impact score 0–10 based on EDHREC
inclusion rate, synergy score, price, and combo relevance. Card data is sourced from
Scryfall.
