Known issues & what's next

This page is the feedback loop. Report something (in-app Feedback button, Discord, Reddit) and it shows up here: first as a known issue, then as fixed. Updated as things land.

Known issues

The Hobbit runs on model ratings, not 17Lands data. The set is scored from card text before a single real draft exists, so treat its numbers as a strong first draft, not a verdict. Pack odds come from WotC's own collation article. Real pick data lands a week or two after Arena launch and the set recalibrates in place. The set picker badges this.
The Hobbit's synergy model is estimated, not measured. Our main read on which cards belong together normally comes from real decklists, which don't exist before release. For The Hobbit we estimate it from color and tribe instead. It's a good approximation of the shape, but it can't know that two specific cards combo. Real decklists replace it with the 17Lands recalibration.
The model likes removal a little more than winning drafters do. Simulated pools run slightly more removal than real 5+ win pools. Known, measured, and the fix is structural (not a quick tune), so it's queued rather than patched.
Mana-producing creatures score a touch low in draft. Same class of issue as above: the count-based carrots need per-set direction, which is a planned rework.
Strixhaven auto-builds run leaner mana fixing than real winning decks. If you'd keep a fixing land the builder cut, that's useful feedback: tell us which one.

Next up

The Hobbit, recalibrated. The set is already live, ahead of its Aug 11 Arena launch. Once 17Lands publishes real draft data we recalibrate the ratings on actual picks and rebuild the co-occurrence model from real decks. Nothing to do on your end: the set upgrades in place and the confidence badge moves with it.
Arena overlay. A desktop overlay that scores picks inside the MTGA client, Untapped-style, with one-click deck build. In development.
Known-issues intake. Anything testers report during launch week gets triaged onto this page.

Recently fixed

2026-08-08: The Hobbit's card ratings were rebuilt from scratch. We cross-checked the old list against ten community tier lists and found three real problems: removal was rated too high, famous characters were graded on their fame instead of their text, and the entire common land cycle sat in the bottom tier. The new method keeps only the model's ordering of cards and maps it onto the same scale every data-backed set uses, so a bomb reads like a bomb instead of running off the top of the chart. We tested it by re-rating four sets we do have real data for, then replaying real drafts: it matches winning drafters' actual picks about 10 percentage points more often than the old method. Built decks also stopped running zero removal, which was a flag-wiping bug in the first pass. Ratings still get replaced with real 17Lands data days after release.
2026-08-07: draft bots now raredraft like humans. They used to pick on card strength and lane fit alone, so a rare nobody's lane wanted just kept getting passed, sometimes all the way to the wheel. Measured against real 17Lands drafts: human tables let about 1 rare in 20 survive to the wheel, our bots let 1 in 5 through, and The Hobbit was the worst offender. Bots now take rares at human rates, tuned pick by pick against real draft curves on every data-backed set. (Reported by a user, and they were right.)
2026-08-05: long-press to enlarge a card now works on phones and tablets. It was a mouse-only trick before, so on real touch screens the big card either never appeared or appeared and refused to leave. Swiping between cards in the pack and the Guides menu links also got fixed on the way through. (Reported by a user, and they were right.)
2026-08-04: The Hobbit is drafting-ready a week before it hits Arena. Ratings, archetypes, and pack odds are in place on day zero, flagged as model-rated until real data arrives.
2026-08-04: Marvel Super Heroes now runs on full 17Lands game data. Ratings, archetype signals, and baselines are all rebuilt on real games instead of pick order, which closes the draft-data-only caveat that used to sit on this page.
2026-08-04: mana fixing is counted honestly now. A card that only makes its own colors was being treated as a splash enabler, which nudged both pick scores and auto-builds toward splashes the mana could not support. Own-color producers now count as mana sources and nothing more, a batch of missed mana producers got swept into all four sets, and every baseline was regenerated on the corrected math.
2026-08-04: an Assist toggle. Turn scores, rankings, and auto actions off in one click and draft the pack cold, then turn it back on whenever you want the read.
2026-08-04: enlarged cards no longer get stuck on screen when the pointer leaves in an odd way.
2026-07-27: auto-build no longer splashes a color it can't actually cast. Two mana-math bugs, same root: a 3-mana artifact that taps for any color was counted as a real source for a one-mana spell (it isn't, you're three turns late), and the check that refuses cheap off-color cards only looked at double-pip costs, so a single-pip one-drop walked straight past it. Reported on r/lrcast, where a pool with two white cards was building into white on a handful of Plains. Rebuilding that pool shape, it now stays two colors with none. (Reported by a user, and they were right.)
2026-07-26: dual-land pick values audited against 1500 real winning drafts per set: found and fixed two real bugs (a conditional-land scoring leak, and practice packs dealing the wrong number of dual lands), then verified the tuned values now match how winning drafters actually take fixing.
2026-07-26: Arena-style drafting on phones. The pack is now a compact art grid with score badges, tap a card for its full breakdown, swipe to compare the next pick, and commit with a real Pick button. Rotate to landscape for a wider grid with the scorecard docked beside it.
2026-07-26: first real mobile pass. Deck cards are readable list rows on phones, the header gets out of your way when you scroll, tap any card for its score breakdown, and the filter panel tucks behind a toggle. (Reported by a user, and they were right.) More polish coming; if your phone still fights you, tell us the model.
2026-07-23: deckbuilder no longer overflows the viewport on narrow screens.
2026-07-23: score-driver bars no longer show a "-0.00" label.
2026-07-23: "Regenerate Auto Built Deck" is now instant when the pool hasn't changed.

Spotted something wrong? The Feedback button in the draft app goes straight to the dev. "This pick score is nonsense because X" is exactly the kind of report we want.
