Even more than 0.15.3, this patch is primarily focused on bug fixes.

Prospective fix for occasional deck editor & collection crash / slow filter response

Increased chance of getting wild cards in packs and single card rewards

Added feature to make it easier to open multiple packs in a row. Start by clicking the first pack, after which you can press or hold spacebar to continue opening packs

Fixed a crash that could sometimes occur while crafting

Fixed a bug where your turn timer could expire immediately after reconnecting

Throttle GPU usage when application is minimized or not focused (Windows only)

Adjusted idle emotes to occur less frequently (and not at all in bot games). Custom idle emotes added for most portraits

Fixed favorite card material/trim functionality

Fixed a bug where the card collection would start at the bottom instead of the top

Added a scroll bar to the card collection

Fixed a bug that prevented Xerxian Saboteur and Forgeling demise effects from working.

Reincarnation should now work properly

Fixed a bug reported as “suppressing Herald of Pestilence opposite a Serpent on a Serpent’s Den enchantment with Singing Stone in play kills the Serpent.”

Damage effects with a value of 0 (eg Extract Life cast with 0 mana or Herald of Death demise with 0 attack) no longer deal damage to minions with Fragile

Fixed a visual bug that could cause the mana bar to show incorrect mana/gem counts when casting certain cards quickly (reported as Blood Moon followed by Panic Raider in quick succession)
