Mulligan Labs — Ben Green

Mulligan Labs is an independent project built under my LLC, 707 Labs. It lets Magic: The Gathering players test and play their Commander (EDH) decks online in real-time multiplayer — with seamless deck imports from Archidekt and MTGGoldfish and live card data from Scryfall. This project gave me hands-on experience with the full product lifecycle outside of a corporate environment.

Challenge

Commander players have no great way to test decks against real opponents without physically meeting up or using clunky workarounds. Existing digital tools are either solitaire-only, paywalled, or lack real deck import options. The goal was a frictionless, free-to-use multiplayer table where any player could import and playtest a Commander deck in minutes.

My Role

I led all design and contributed to frontend development. From defining the product concept and information architecture through visual design to working in code alongside my co-founder — this project sharpened both my product thinking and my ability to collaborate directly in the codebase.

All Under One Roof

Mulligan Labs is the most feature-rich way to play Magic: The Gathering online today — a complete Commander table with phase tracking, life and counter management, library search with Scryfall syntax, quick-actions like Scry, Mill, and Proliferate, plus customizable layouts, foil shimmer, and CRT effects. It also doubles as a brewing workshop: import a deck and get AI-powered suggestions to refine your list. Play, test, and improve — all in the same product.
