Vibe Brewing

Describe the deck you want. Get a real one back.

Type the vibe of a Commander deck in plain language. The Strategist writes a plan, never a card list, and a deterministic assembler retrieves every real card from the live catalog under Commander's own rules. Invented, illegal, and off-color cards are impossible by construction.

Vibe Brewing needs a ManaLotus account. Each brew is metered per deck; pricing isn't final yet, and we'll publish it before anything charges.

You describe the vibe

"Vampires that bleed the table dry while I gain life."

The Strategist writes a structured plan

A deterministic assembler returns a real deck

Illustrative. The plan is concept-level (never card names); the assembler retrieves the real cards from the catalog.

Grounded, not guessed

A plan from the Strategist, real cards from the catalog

A deck generator that lists cards is guessing from memory, so it can misremember a name, invent one, or hand you a card that isn't legal in your colors. Vibe Brewing splits the job: the Strategist judges strategy, deterministic code retrieves the cards.

0
Fabricated cards

The Strategist never names a card, so an invented name can't reach the deck

1 plan
From the Strategist

The deck is built from a single structured plan and deterministic catalog reads; a separate Critic grades the finished deck

100
Cards per brew

A full Commander deck, singleton and inside the commander's colors

5
Partner Mechanics

The legality engine models every pairing rule, never a fuzzy 'partner' bucket

Impossible by construction

The Strategist never picks a card

The Strategist reads your vibe and emits a structured plan over a fixed vocabulary of strategies and gameplay concepts. It names a strategy and describes a direction; it never writes a card name. A deterministic assembler then turns that plan into a deck by retrieving real cards from the catalog, so 'no fabricated cards' is structural, not a hope.

  • The Strategist outputs a plan of concepts and effects, checked against a fixed vocabulary
  • An unrecognized tag is rejected before retrieval, not smoothed over
  • Every card in the deck is a real printing the assembler pulled from the catalog

The Strategist call shapes the plan; the cards are read from the catalog, never written from memory.

Format rules first

It plays by the format's rules, all of them

Retrieval is filtered to the commander's color identity and to cards legal in Commander before a single card is picked, and the deck comes back singleton. The same platform legality engine also models the format's real pairing rules, keeping Partner apart from Friends forever apart from Partner with, so ManaLotus doesn't collapse them into one fuzzy 'partner' notion.

  • Every candidate is on the commander's color identity and Commander-legal
  • Singleton, enforced at assembly: one of each card, a full 100-card deck
  • The Commander legality engine distinguishes all five Partner Mechanics, rather than one fuzzy 'partner' bucket

Legality filter

Color identitysubset only
Commander formatlegal only
Copies per card1 (singleton)

Color-identity, format, and singleton constraints run at retrieval time, so an off-color or illegal card is never a candidate.

Bracketed and graded

A read on the deck, and on what it costs you

A brew doesn't just hand you a list. It reads the assembled deck back to you: a Commander Bracket estimate, 1 to 5, from the actual cards, a Critic that grades the deck against its own theme and flags where it drifts, and an ownership overlay against your collection. The bracket is honest about its limits: it reads Game Changers, fast combos, and mass land denial off the real list, so it tops out at Bracket 4. Bracket 5 (cEDH) is a builder-intent call the cards alone can't make.

  • A Commander Bracket badge, 1 to 4 (estimated), read off the real cards; Bracket 5 (cEDH) is a builder call the cards alone can't make
  • The Critic judges the real cards against the plan's theme, not just bucket counts
  • An owned-versus-buy overlay resolves the deck against what you already own

After the deck is built

Owned vs. buyoverlay

These run after assembly, on the deck you actually got, not on a promise. The bracket recomputes from the live catalog, so it is never a stale stamp.

The difference

Most deck generators write a list. We retrieve one.

The gap is not a smarter generator. It is the division of labor: the Strategist judges strategy, and it never names a card.

The way deck generators usually work
With ManaLotus
A deck generator writes a card list from memory, so names get misremembered or invented
The Strategist writes a plan; a deterministic assembler retrieves every card from the live catalog
Off-color or out-of-format cards slip into the list
Retrieval is filtered to the commander's color identity and Commander legality before a card is ever picked
A flat list with no read on how strong it is or what it costs you
A Commander Bracket estimate, a theme grade, and an owned-versus-buy overlay on every brew
You can't tell what is real until you look each card up
Every card is a real printing from the catalog, checked legal before it's picked
