What are the odds you'll hit your next land drop?
Today Manasight v1.2.0 ships the deck tracker. At the top is its Land Drop Forecast: probability across the next one, two, and three draws.
It's turn four. You're on three lands. Your hand has a five-drop and a one-mana removal spell. Do you keep developing toward the five-drop and risk another wasted turn, or play around the miss and use the removal you've been sitting on?
Every Magic player has had this turn. Manasight's new deck tracker shows you the odds, live, on every draw.
Land Drop Forecast
Manasight shows the probability of drawing at least one land in the next one, two, and three draws. Three cells, color-tiered, updating live as the library state changes.

In the screenshot above: 37% on your next draw, 60% by the one after, 75% by the third. The cells walk from yellow to green. That's the recommendation: probably miss on the next draw, favored to hit by the one after, comfortably likely by the third. With three lands and big spells in hand, the call is to keep the removal and develop toward the five-drop.
Most deck trackers show next-turn land probability: the chance of hitting on the very next draw. Manasight extends to three draws because three draws is the planning horizon that's most useful. Manasight does the math for you, every draw.
Deck Tracker
Below the Land Drop Forecast is a live list of every card still in your library, sorted by likelihood of drawing it next. Each row shows mana cost, copies remaining, and single-draw probability. As cards leave the deck, the list updates in real time.
Simple math can't tell you your next draw, but it can tell you what to plan for.
Three founding features
Post #1 named three features for Manasight at launch: an in-game action log, a deck tracker, and a connection indicator. The action log shipped as the Play-by-Play Log. The connection indicator shipped as Arena Signal. Today the Deck Tracker ships in v1.2.0.
Three founding features. All live.

What's next
What shipped today is the first version. Coming up: card image on hover for every card in your deck, colored mana pips in the mana costs, and live data signals when panels are collapsed. I have even more ideas for what comes after that.
Give it a try. If something feels off, or if you have thoughts for what would make it more useful, please let me know.
I'm Tim and I'm building Manasight. The deck tracker is in v1.2.0 now: free across every Arena format, on Mac and Windows. Try it at manasight.gg.
