Hmmm, looks like the devs are not giving up on evolve shaman...
Sigh. Well, at least Rabble Bouncer* could be proven useful in this deck.
 Of course it's a worse Ancestral Spirit. With all of the high-cost, weak stated minions nowadays (and in the next exp.) this card can backfire a lot. Concede shaman was strong and consistent. This card is purely for fun.
At least, Unstable Evolution will live on in some fashion after rotation. I highly doubt this spell will be used much but I am happy to see that Evolve continues to be part of Shaman. *votes as playable*
Although I absolutely love Evolve Shaman and it's still currently my favourite deck, I feel that this card is just too slow for the most part. Seeing allot of boring people contentiously spam out "wOrsse Anceeestral spoorut"... some people need to learn to have some fun.
