Battlegrounds Updates


Zephrys, The Great
  • Three Wishes [Cost 4]
    • If you have two copies of a minion, find the third. (3 wishes left)

Zephrys the Great has been added to Battlegrounds

Players with Battlegrounds Perks will have early access to Zephrys, The Great before the Hero is formally released on November 5.

Battlegrounds Parties Adjustments

We’re making small adjustments to Battlegrounds Parties during matchmaking and in post-game rating updates to address the potential advantages that come with queueing as a group.

  • Post-game rating updates will no longer include results between players within the same group. When you queue Battlegrounds with a group now, your rating gains are only based on your results against players outside of your group.
  • You'll now be matched based on the highest player rating in your group, rather than the group's rating average. End of game rating updates will take this rating disparity into account.
  • We’ve disabled 2-4 player Battlegrounds Parties for players above 10,000 rating.

Standard Balance Updates
  • Old: [Cost 1] → New: [Cost 2]
Evocation Oldcardchanges_arrow.pngEvocation New
Astromancer Solarian
  • Old: Solarian Prime [Cost 7] → New: Solarian Prime [Cost 9]
