Vibe Brewing
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.
Vibe in · real deck out
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 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.
The Strategist never names a card, so an invented name can't reach the deck
The deck is built from a single structured plan and deterministic catalog reads; a separate Critic grades the finished deck
A full Commander deck, singleton and inside the commander's colors
The legality engine models every pairing rule, never a fuzzy 'partner' bucket
Impossible by construction
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.
Where cards come from
The Strategist call shapes the plan; the cards are read from the catalog, never written from memory.
Format rules first
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.
Legality filter
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 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.
After the deck is built
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
The gap is not a smarter generator. It is the division of labor: the Strategist judges strategy, and it never names a card.
Pick a commander, describe the vibe, and get a real, Commander-legal deck back. Vibe Brewing needs a ManaLotus account; brew pricing is still being set.
