Mulligan Labs
A free online multiplayer client and deckbuilder for Magic: The Gathering.
The problem
Playing Magic online usually means a download, an account, and a client that fights you — especially for multiplayer Commander, where four people have to share one board. We wanted a table you could open in a browser tab and invite friends to in seconds.
Our approach
We built the whole thing to run in the browser: real-time multiplayer, nothing to install, no account needed to start a game. The deckbuilder and the play client share one codebase, so the deck you build is the deck you play. And like a real table, the app keeps the shared game state while players make the calls — which is what lets it support every format instead of just the few a rules engine could encode.
What shipped
A free, browser-based client and deckbuilder that seats up to four players in any format — open a tab, share a link, and play.
How it's built
SvelteKit on Cloudflare's edge network, with real-time multiplayer running in the browser.
