So the problem with reverse ooze here is that you want to run it in a deck with a way to get guaranteed value from it, which means lots of weapons. Which also probably means that you are going to get back a Wicked Knife, King's Defender, or Blood Razor rather than that sweet legendary weapon, Atiesh, or Arcanite Reaper. With the awful stats (seriously 3 mana for a 1/3 is godawful), it seems like it is only useful as a combo piece rather than as a core part of a weapon deck. No thanks.
The Druid weapon is interesting in the same way that Kun is. Lots of combo potential in a deck like Big Druid where you are already running Medivh & co. The 1 attack makes your hero power slightly better (and a LOT better if you have the DK out). But needing to chew through 5 charges before you can get the effect is a big drawback. I also wonder if they will be printing a way to break your own weapons in the set. Without that even playing this exactly on curve you only get a 1 mana ramp. Getting a full refresh is pretty good though so hard to say. Definitely worth a try in something like Big Druid.
