Ikoria: Lair of Behemoths Premier Draft

Adjusted Rank-Based Matchmaking for Premier Draft
- Developer’s Note: As some of you may have noticed, there were certain scenarios where you were being matched against somebody with a much higher (or lower) Rank than yours – this should address that issue. Regardless, players were still being properly matched on their current W/L record (Ranked draft formats use both your rank and your win/loss record when searching for an opponent).
Adjustments to opening-hand algorithm for Premier Draft
- Developer’s Note: We intend for best-of-one formats to use a modified opening-hand algorithm which pulls multiple potential opening hands and chooses one; Premier Draft was operating contrary to that, and we have fixed it accordingly. To stave off any conspiracy theories, it was previously using our best-of-three opening hand rules (which pulls one, and only one opening hand).

"Checking for Updates" should take significantly less time.
Autotap and Smart Stops once again recognizes when certain modal spells (e.g. Thassa’s Intervention) can cast one mode but not the other.

Sideboarding a designated Companion into your mainboard during best-of-three matches should now function correctly.

Lurrus of the Dream-Den now correctly handles X values in converted mana costs (For spells with X in their mana costs, use the value chosen for X to determine the spell’s converted mana cost. For example, if a permanent spell costs xWhite, you could cast it with X as 1 but not as 2).
Jubilant Skybonder’s cost increase now functions correctly when there are multiple instances of this card on the battlefield.
Players can now appropriately select cards from their graveyard with Mausoleum Secrets.
Setting Zirda, the Dawnwaker as your Companion will no longer cause the game to crash if you have cards with the Ascend keyword ability in your deck.
Mythos of Brokkos should no longer bring back non-permanents from the graveyard to your hand if cast with no permanents in your graveyard.
Mutated creatures are now counted as one creature for Settle the Wreckage, as they should be (702.139c of the Comprehensive Rules, if you're curious).
A mutated Cavalier of Thorns should no longer be able to target "itself" if you chose to exile it when it dies.
