Deck Lab

What this surface is

Deck Lab is where target decks live. A target deck is a list you want Pegasus to evaluate against your collection. Deck Lab handles creation, editing, format selection, readiness display, and archival. It does NOT include analysis (see Quick Analysis) or versioning depth (see Deck versions) — those are separate surfaces reached from within a deck.

Where to find it in the app

Navigate to /decks from the main nav. Lists every target deck with its current readiness badges and last-edited timestamp.

Layout

Region	Purpose
Top toolbar	”New deck” CTA, search, filter (active / archived), sort
Deck grid	One tile per deck — name, format, badges, last-edited
Tile detail	Click to enter the deck editor + analysis view

New deck form

Field	Type	Required	Notes
Name	text	yes	Free-form; rename later anytime
Format	dropdown	yes	TCG, OCG, Goat, Edison, HAT, others — drives every downstream evaluation
Initial state	radio	yes	Empty / Paste YDK / Duplicate existing deck
Description	text	no	Optional one-liner shown on the tile
Tags	chip input	no	Free-form tags for grouping

Cuidado

The format field is the single most consequential pick on this form. It determines banlist, copy limits, and which meta the analysis compares against. Change it after creation only via deck settings — do NOT recreate the deck.

Readiness layers

Every deck shows three independent badges that answer different questions:

Badge	Question	Possible states
Legal	Does the active banlist allow this list as-is?	green / amber (warnings) / red (illegal)
Buildable	Can you assemble this from inventory now?	green (own all) / amber (close — missing N) / red (missing many)
Cost	What would the missing cards cost at current prices?	green (≤budget) / amber (over budget but viable) / red (far over)

A deck can be legal + unbuildable, buildable + over budget, or buildable + fully owned but structurally fragile. No single badge means “this deck is fine” — read all three.

Deck editor

Region	Purpose
Main panel	Cards in the main deck (40-60) — sorted by your chosen criterion
Extra panel	Extra deck cards (≤15) — analyzed jointly with main
Side panel	Side deck cards (≤15) — evaluated separately against format meta
Search panel	Format-filtered card search; drag to a zone to add
Deck stats	Live counts: main / extra / side / total ratios
Toolbar	Save, Save as version, Export YDK, Settings

Card actions inside the editor

Action	How
Increment / decrement	Click + / − on the card chip
Remove from deck	Right-click → Remove, or quantity to 0
Move between zones	Drag, or right-click → “Move to …”
Open card detail	Click the card art
Bulk paste	Toolbar “Paste cards” button

Archive flow

Step	Result
Click “Archive” in deck settings	Confirmation modal opens
Confirm	Deck moves to Archived; readiness/acquisition stop including it; version history preserved
Restore (later)	From /decks?filter=archived — restores all commitments

Archived decks vanish from active scoring but stay reachable via the /decks?filter=archived view.

States and badges

Badge / state	Meaning	When you see it
Legal: red	Banlist violation	Card limit exceeded or banned card present
Legal: amber	Banlist warning	Restricted card at limit (no headroom)
Buildable: green	All cards available	Inventory satisfies the deck
Buildable: amber	Missing some	Hover shows count of missing copies
Buildable: red	Missing many	Acquisition surface lists the shortfall
Cost: gray	No price data	Some cards lack a public price feed
Cost: green	Within set budget	Set via account settings
Cost: amber	Over budget (≤2×)	Manageable with planning
Cost: red	Over budget (>2×)	Reconsider scope
”Review” callout	Buildable but structurally weak	Run Quick Analysis for details

Interactions

• Click a deck tile → opens the editor + analysis view
• Cmd/Ctrl+S in editor → save current state
• Cmd/Ctrl+Shift+S in editor → save as new version (see Deck versions)
• Drag card from search → zone → adds 1 copy
• Drag card from one zone → another → moves
• Toolbar “Export YDK” → downloads .ydk for offline editors

Edge cases

Cuidado

• Format mismatch on import. Pasting a YDK from a different format raises a banlist warning storm. Change the deck’s format in settings rather than fighting the warnings.
• Card not found in catalog. Very recent releases sometimes lag the catalog by 24–48h. Add manually via Inventory in the meantime.
• Side deck cards in main panel. Some YDK exports merge side into main. The editor catches and warns; manually re-split.
• Over the 60-card cap. Permitted by the rules but flagged with an info chip — most evaluations assume 40-card builds.
