Extra Turn – live deck tracker overlay for MTGO. Open beta
I'm the dev, so: self-promo warning up front.
MTGO writes a log file for every game you play. I've been building an overlay on top of those: while you play it shows what's left in your library, the odds on your next draw, and how many lands you have left, and afterwards it keeps your match history and matchup win rates locally. It's a passive reader. It never touches the client, no injection, no automation, nothing that plays for you.
There's also a Twitch extension, so viewers can hover the cards on your stream and read them. First one of those for MTGO as far as I know.
Open beta, Windows only, no account: extraturn.gg/download (there's a paid tier for the draft assistant, but everything I just described is free.)
What I actually want from this post is people playing formats I don't. The whole thing lives or dies on counting cards correctly and I've mostly tested it against my own matches and a tiny closed beta, if it miscounts your library, or misreads a concede, a timeout or a bye, that's what I want to hear about.
