Let's create a Shaman Imprisoned Demon - Challenge?

I thought it was strange that all classes received an Imprisoned "Demon" besides Shaman.

So as a fun little challenge I want to see what you guys can come up with for an imprisoned Demon for Shaman!

Here are a couple designs I came up with in a couple minutes.

Invest a lot of Mana and lose a bunch of tempo to set up a combo or clear on a later turn.

Something to round out the Totem Shaman archetype that's been very loosely pushed throughout the past few expansions.

I submitted this for the WCDC this week. Also, Rogue has none too.
