  • The new evolved minion will be exhausted by summoning sickness and unable to attack this turn, unless it transforms into a minion with Rush or Charge.
  • For general notes on the mechanic, see  Evolve.

Trivia[edit | edit source]

  • Unstable Evolution used to be "Repeatable this turn" instead of "Echo". This was changed because of  Radiance of Azshara which causes Unstable Evolution to discount its cost to 0 mana allowing the player to play infinite amounts of Unstable Evolutions in one turn. Unlike  Radiant Elemental or  Sorcerer's Apprentice, Radiance of Azshara is a Shaman card which can be included alongside Unstable Evolution which always reliability achieve this interaction. This change was made to pre-emptively prevent the interaction.
