Good analysis and I think you may be right, One thing I'd like to add about your dopplegangster + DK Thrall point is that you have a significant chance of getting baron geddon which destroys a lot of the value that you just got through the double evolve, especially if your opponent has a damage-based aoe removal in hand.

You might be right about what you say but don't forget about the cards like Moat Lurker and Bomb Squad. The hero card gives you an opportunity to get rid of its harmful effects like a cheaper version of Master of Evolution and you don't have to waste your Evolve for only one Moat Lurker. There are also good battlecry cards with bad stats like Bonemare, Big-Time Racketeer and variaties which i don't remember now.

You can use a Darkspeaker for buffing some cheap taunt minion and after that you can evolve it.

You can also try this hero card with a type of a C'Thun deck, which contains a lot of battlecry minions.

It is also a good tech with Jade Golems

Also it is a good card with a murloc deck which Shaman has already a quest about it. You can boost your murlocs and some murlocs like Corrupted Seer can evolve well.

This card is bringing more things then we thought. It has a potential for the existing cards which never find some place in constructed.
Also the cards which were well at constructed and no more find a place like Tinkmaster Overspark can be seen in ranked plays again.

Ofcourse they all are in paper. As you said, we shouldn't overestimate any card but what I'm trying to say is we shouldn't underestimate them too.

I'm trying to direct your attention to other techs than evolve-based decks. This card is more complicated than it seems.

Marsh queen had too much condition + reward was so slow compared to that condition but to use this you just need two cards on the board
