Mana curve
Nonland cards, including commanders when resolved. Mana value 7+ grouped.
DEEP CUTS EDH / THE DECK PHYSICIAN
The Deck Workshop.
Diagnose the mana, curve, consistency, legality and table expectations of a forgotten commander deck. Review cuts and upgrades yourself—no mystery black box.
NEW / DEEP CUTS DECK GENERATOR
Build the impossible.
Generate a complete Commander draft around an obscure legend. Cards come from live Scryfall searches, with color identity and format checks. This is a new deck foundation, not a playtested optimization.
Choose a commander and a strategy to begin.
01 / IMPORT YOUR PATIENT
The decklist
Commander cards count toward 100. For legal partner combinations, use two lines.
IMPORT A PUBLIC DECK URL
Uses Commander Spellbook's published decklist import service for public Moxfield, Archidekt, Deckstats and TappedOut URLs. Private decks, unsupported sites, and changed provider formats may require a text export.
Paste a deck or add cards from the Card Library.
COMPLETE THE DECK
Suggested additions
Estimated card prices, excluding shipping and unavailable printings.
These are proposals based on mana, card roles, commander text, color identity and approximate prices—not playtested recommendations. Review every addition before applying.
COMMANDER BRACKET TARGET
Your selection is a target, not an automatically assigned score. The tool checks known Game Changers and red flags; it cannot reliably infer game speed, combos or intent.
MY SAVED BREWS
Save up to 12 deck snapshots on this browser. Analyze changes before saving a snapshot. These are local—not cloud synced.

03 / FIELD DIAGNOSTICS
The Apothecary's Notes
Role estimates and probability calculations based on your resolved card list. Advisory, not a playtest or a certified bracket rating.
Analyze a deck to unlock the complete workshop report.
Opening-hand odds
Exact hypergeometric calculations, on a 100-card deck assumption, without mulligans. Ramp probability counts cards classified as ramp, not whether their mana costs can be paid.
Deck roles
Oracle text heuristics; some cards fill multiple roles. Confirm edge cases manually.
Strategy / table feel
Experimental pattern flags, not ML win-turn, archenemy scoring, or combo-proof classification.
05 / VERIFIED COMBO INTELLIGENCE
Combos & bracket signals.
Commander Spellbook detects complete combos and combos missing one piece, plus bracket-relevant effects. Results cite the actual combo database instead of claiming to discover new infinite loops.
Analyze your deck and click Check My Combos.

Brackets & disruptive mechanics
No Spellbook analysis yet.
Source: Commander Spellbook ↗. Incomplete or ambiguous card names can produce incorrect results. Combo prerequisites may still prevent execution in a real game.
06 / RULES DESK
Ask the card. Read the ruling.
Look up official card rulings through Scryfall and verify interactions in the latest Magic Comprehensive Rules. This is a sourced rules lookup, not a generative Judge chat.
08 / RECOVERY-KEY CLOUD VAULT
Keep a deck across devices.
This is a private-key vault, not an email or social-media account. Create a 256-bit recovery key, keep it secret, then use it to load or update one cloud deck on another device. The site database stores deck text, so do not treat this as end-to-end encrypted storage.
Create a vault only after adding a Commander deck. Losing your recovery key means you cannot recover the cloud deck.
04 / COLLECTION & BUY LIST
Cards you own. Cards you need.
Paste a list from a collection export with one quantity and card name per line. This stores a local copy in your browser; it is not synced to an account.
0 cards in collection
Import a collection list to see what your deck still needs.
Research, export, and shop.
Keep working across the Magic community. External sites open in a new tab. Deck export is plain text; some sites require you to paste or import it after opening.
Advanced features in development
Hosted deck imports and combo detection use Commander Spellbook; a guided commander-aware builder creates editable 100-card drafts, while cloud share links provide read-only snapshots. Full authenticated account sync, generative rules-chat answers, and trained ML win-turn predictions are still unavailable. Current probability and health indicators are experimental.
