This patch is about seeing more before you commit. Ranked now shows every league the same pool of rules, so what you practice is what you play. Match history and the draft both gained quick hover previews, and the tournament bracket got a readability fix.
Improved
Every league plays by the same rules
Ranked now draws from the same pool of rules for every league. Before, lower leagues could only ever see a smaller set of possible rules while higher leagues saw more, so the rules you practiced against were not the rules you would meet as you climbed. Now the pool is identical for everyone, and only your tier decides how many rules stack on a match, up to three. Ghost Ranked also rolls a little richer, two to three rules per match instead of the old lighter roll.
Hover your match history for a quick preview
On your match history you can now hover a match to see a quick preview: your commander, the rulesets and mana cap, and your opponent's commander. It makes finding the exact game you are looking for much faster, with no need to open the replay first.

Preview your picked cards in the draft
In the draft, hovering one of the seven cards you have picked at the bottom now opens the same enlarged preview and ability description you get when picking from the pool above. Double-check a card's ability without losing your place in the pool.

Fixed
Cleaner tournament brackets
Fixed two bracket display bugs, most visible on the losers bracket. A finished match no longer shows a blank status bar under the two players, and the rounds no longer look crushed together into a single squashed row. The bracket structure reads clearly now.

More clarity and quality-of-life touches are on the way. Thanks for playing the alpha and sending us your replays and reports, they are what shape these.
