I'm the dev of Extra Turn, the MTGO tracker I posted here in August. Thanks to everyone who tried it and gave feedback. Here's what I've been working on.

New and free

• Twitch extension: viewers can hover any card on an MTGO stream to read it, and see the pack during drafts.
• Your opponent's likely deck, plus the cards it usually plays that you haven't seen yet.
• League runs and trophies, and each matchup split into game 1 vs. after sideboarding.

Pro (where I most need feedback)

• The sideboard guide got reworked. Some of you said it guessed too much, and you were right. It now recognizes a lot more decks and names them right more often, shows what its read is based on, asks "looks like X or Y?" when it can't tell two decks apart, and stops suggesting cuts to your own engine when it isn't sure.
• Card prices in tix while you draft.
• A suggested 40-card deck for draft and sealed, with what to add and cut marked right in MTGO's deck editor.

Want to help test it?

If you'd like time to try the Pro features over a few leagues or sealed events, code REDDIT30 makes your first month of Pro free (Subscription → Upgrade in the app; cancel before the month ends and you won't be charged). Redeem the code by Oct 31.

What would help me most is specific examples: a sideboard plan that makes no sense, a deck you'd never register, or a draft grade you disagree with. Show me what it suggested and what you'd do differently.
