The Nerd Leagues Deck Builder: A Tour

The Nerd Leagues deck builder is where your decks live. Build one from scratch, pull them in from Moxfield or Archidekt, sort them into folders, and open any deck in a card-by-card editor with stats, combo detection, and a playtester. It is at nerdleagues.com/deck-builder and needs an account.

Your Decks

Your Decks is the hub. Three links run across the top — My Decks, My Collection (cards you own, with purchase prices and notes), and Community Decks (everyone's public decks). Below that is a filter bar with a deck search box, a format filter, a sort control (Recently Updated, Recently Created, Name (A-Z)), and a toggle between two card sizes. A sidebar on the left holds your folders, plus Recent and Most Viewed shortcuts.

Starting a deck

New Deck opens two choices:

• From Scratch — name, format, an optional description, and visibility.
• Import from Platform — Moxfield or Archidekt. Paste a profile URL or just a username, tick the decks you want off the list it finds, pick a folder to drop them in, and import the batch in one go. TappedOut and Deckstats are listed as coming soon.

The format list covers EDH, PDH, Standard, Modern, Legacy, Vintage, Pioneer, Pauper, Historic, Brawl, Oathbreaker, Premodern, Penny, and Custom. Visibility is Public (listed on Community Decks), Unlisted (anyone with the link), or Private (only you); a deck you create by hand starts public.

Folders

Folders nest one level deep — a folder can hold subfolders, and those hold decks. Drag a deck onto a folder to file it; drag folders themselves to reorder or nest them. The ... button on a folder (or a right-click) covers rename, new subfolder, move, color from a large swatch grid or a custom color, and delete. Deleting a folder does not delete the decks in it.

You can also select several decks at once and move them, change their visibility, or delete them in a single action.

Inside a deck

Opening a deck gives you the editor. Cards are split across four zones — Main, Side, Maybe, and Tokens — with the commander in its own slot beside them. Add Cards opens a live card search, and next to it sit Bulk Import for pasting a list and Advanced Search for filtering by color, mana value, type, oracle text, rarity, set, and a price range — or by raw Scryfall syntax if you already know it.

The toolbar carries the rest:

• Stats — the Deck Statistics panel: mana curve, card type breakdown, land analysis, and a sample opening hand.
• Combos — checks the deck you have open against the Commander Spellbook database and lists the combos in it, plus the ones you are one card away from.
• Playtest — a solo board with rows for creatures, other permanents, and lands, a turn counter, a life total, and Draw, Shuffle, Search, and Scry. Enough to goldfish an opener without leaving the page.
• Import and Export — import from a platform or a pasted decklist; export as plain text, MTGO, Arena, or a Tabletop Simulator object. Keyboard shortcuts: S, I, E.

Each deck also has its own tags — your own labels, in your own colors — so you can group the list by Ramp, Interaction, or Wincon instead of by card type. Tags survive a Moxfield round trip as #hashtags.

Sharing a deck

Every deck has one URL. You get the editor on it; everyone else gets the same layout read-only, so a link you paste in a Discord channel opens the real deck rather than an export. A private deck shows a lock instead, to everyone but you.

Where to go next

Decks are also the unit leagues rate — Adding Decks to an MTG League covers putting one into a league and what that does to its record. To start from a preconstructed deck instead of an empty one, browse the Commander precons.
