Dylan Matthews · Commander Deck Generator

Five decks from real generator runs, with everything the generator recorded.

The generator builds a 99-card Commander deck from a commander, a budget and an optional strategy. Deterministic code does the filtering, optimization and legality checks. A language model writes the commander profile and reviews risky picks. The hosted generator is private, so this gallery shows recorded builds instead of a live form.

The builds

Commanders were picked for spread across colors, budgets and strategies, not for strength or popularity. No build was re-run or replaced to get a better result. Every build is shown, including its warnings.

Total spend$0.0062 estimated for the five builds (35,275 input and 24,670 output tokens). Two earlier attempts were stopped before finishing, one to record role targets and one to match the web route's selection policy. Their output was discarded for those reasons alone, not for quality. They cost $0.0019 more.
