After our initial post about patch notes and separate post about Echo mechanic update, Blizzard stealthily added information to the blog about another game mechanics change regarding evolving and devolving effects.

Until the patch, devolving a 0-cost minion had no effect at all with the minion retaining all buffs and damage taken. The same was true for evolving minions with mana costs of 12, 20, and 25. After the patch, evolving effects will cause these minions to be rerolled into minions of the same cost.

What do you think about the change? I'm just waiting for a video clip of Shirvallah + Unstable Evolution combo.

Quote From Blizzard

  • Cards that “transform a minion into a random one that cost (1) more/less”, like Evolve or Devolve, will now always reroll the minion, even if no minion exists in the target-cost minion pool. The minion will be rerolled at the nearest possible cost. Examples:
    • When you Devolve a Target Dummy, because there is no negative-cost minion, it will transform into a random 0-cost minion.
    • When you Evolve a Shirvallah, the Tiger, because there is no 26-cost minion or another 25-cost minion, it will transform into a new Shirvallah the Tiger.
