Binderbrew

Commander deck builder

Build a Commander deck from your Magic card collection

Binderbrew helps Magic players turn an uploaded collection into a playable Commander deck. Pick a commander, set your budget and power target, then get a validated 100-card list plus the missing cards to buy.

Collection-first deckbuilding

Most Commander deck builders start with a blank list. Binderbrew starts with your binder, which makes the final deck more practical and cheaper to finish.

  • Upload or paste a card collection
  • Choose from commanders found in your cards
  • Use owned cards before suggesting upgrades

Commander legality checks

Every generated list is checked against key Commander rules before it is shown as ready to play.

  • 100 cards including the commander
  • Singleton checks for nonbasic cards
  • Color identity validation

A buy list you can act on

Binderbrew separates cards you own from cards you still need, then formats the buy list so it can be copied or exported for marketplace workflows.

Common questions

Can Binderbrew build a Commander deck from only cards I own?

Yes. Use owned-only mode to force Binderbrew to stay inside your collection, or set a budget and maximum missing-card count when you want upgrade suggestions.

What Commander rules does Binderbrew check?

Binderbrew checks commander legality, color identity, singleton construction, banlist status, budget, and 100-card deck size before a list is shown as ready.

Will Binderbrew explain why a deck was recommended?

The review screen includes a deck confidence report with strengths, watch points, role counts, mana curve checks, and why the selected variant fits your goals.
