Vaultforge

About

Build smarter. Build from what you own.

Vaultforge turns your Magic: The Gathering collection into the strongest Commander deck you can build right now — and shows the sharpest upgrade path beyond it.

Why we built it

Most deckbuilders are designed for the vacuum. You pick a commander and they hand you the perfect 100 cards from every printing ever made — most of which you don’t own and can’t afford.

Vaultforge starts from the other direction. Import your collection (CSV, ManaBox, Moxfield, or paste a list), pick a commander, and the composer builds a 100-card deck out of what you have. Then it shows you the optimized version — the same deck with strategic upgrades highlighted — and tells you exactly which cards to buy next, ranked by impact.

What you get

  • ·An archetype-aware composer. The build engine reads ~15 archetypes (Tokens Aristocrats, +1/+1 Counters, Voltron, Spellslinger Control, and so on), detects which fit your commander + collection, and lets you pick up to three to drive the build. Forced includes, weighted card scoring, category target overrides — all data-driven.
  • ·A pilot guide. Per archetype, every saved deck ships with a short strategy brief: what to mulligan to, your mid-game plan, the threats you have to answer first.
  • ·Win-condition detection. If you have an infinite combo, an alternate-win card, a voltron line, or a commander that closes the game on its own, the deck page surfaces it.
  • ·Snapshots and rebuild. Save a snapshot before you tinker; roll back any time. Or rebuild the deck from scratch when your collection changes — the composer reshuffles using the latest cards you own.
  • ·Print-ready proxies. Every saved deck has a print view — clean black-and-white text proxies for playtesting before you commit to ordering anything.

What it isn’t

Vaultforge is not a tournament-grade competitive deck optimizer. It’s also not a marketplace — we don’t sell singles. The composer’s opinionated picks are tuned for casual-to-focused Commander tables, not cEDH.

How it’s built

Open-source TypeScript front to back. Card data from Scryfall. Pricing data refreshes nightly. The composer is a deterministic scorer — same inputs always produce the same deck, so you can share a build link and trust what your friend sees.
