Notes[edit | edit source]

  • Once used, a copy of Unstable Evolution gets added to your hand. This copy disappears from your hand at the end of your turn.
    • While this mechanic is nearly identical to Echo, there are a few minor differences:[1]
      • The copy created from Unstable Evolution is technically a different card from the original.
      • If Unstable Evolution is cast by a minion (Ex. Yogg-Saron, Grand Archivist), a copy will be added to your hand, while Echo cards must be played in order to receive a copy.
      • Echo cards cannot cost less than 1 mana.
  • 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.

Strategy[edit | edit source]

Compared to Evolve, this card is better suited to evolve one or few minions into a much higher costing minion rather than many at once. Since this spell is repeatable, you have better control over the outcome since you can "reroll" an evolution if the outcome is bad or unfavorable.

Since the repeated casts function like any other spell, cards that synergize with multiple spell casts like Arcane Giant and Gadgetzan Auctioneer work well with this card.

Be warned that, when Evolving into a 6-cost or an 8-cost minion, that you have the chance of rolling a Nerubian Unraveler or a Naga Sea Witch, respectively, which may throw off your Evolution chain.

If you are lucky enough to gain a Sorcerer's Apprentice or Radiant Elemental, you can evolve your other minions an almost unlimited amount of times (as you can't evolve them into anything higher than a 12-cost), and if you get an Archmage Antonidas you can gain a lot of Fireballs.

This card has notable synergy with Krag'wa, the Frog, which returns all copies of Unstable Evolution played as fresh copies, giving you many more uses out of Unstable Evolution over several turns.
