Gun Turret: I literally was "????" after seeing this card. Seems like it could be an Epic instead of Legendary, but it'd be a damn good Epic. It's clearly meant as a combo piece, but nothing obvious stands out right now. My question is will the effect proc if it's 1 health but immune from Commanding Shout? I think it does, right? Might be some sort of two-turn kill with Cubes or Faceless and a few whirlwind effects/pyromancer/commanding shout/etc. It's going to be a fun card to try and make work, but it's not apparent if it'll actually be good or work at all.
Cheap Shot: As I mentioned before, Echo cards are so tough to evaluate. The other 2 mana deal 2 in Rogue also Draw a Card or summon a Jade, both of which rarely see play. I don't see this as playable either.
