Reasonable without the battlecry, with a [card]Doppelgangster[/card] effect in a Dragon deck, so it copies buffs. This could be nuts!

Edit: I should have said Galakrond. Posting before my morning tea...

anchorm4n got it, including the reasoning. You're up!

Short and probably too easy:

I come to replace that which removes without killing.

Beware! For I bring death!

Seems a bit weak compared to say [card]Mechano-Egg[/card]. Even if you get a better dragon from Discover, you then have to proc it without the advantage of being a Mech (and magnetize). Seems too hard to make worthwhile.

[card]The Skeleton Knight[/card]?

Seems really good. Just the threat of a 2-cost [card]Fen Creeper[/card] can force some suboptimal plays. Feels playable in any deck that would normally run [card]Time Out![/card], or even aggro Pally as has been pointed out. And it seems like …

If it is played on turn one, it is probably at least as good as [card]Dire Mole[/card] in Arena, since 1/2s tend to live until turn two at least. Maybe later on as well, since you won't always have exactly …

Conditional [card]Abyssal Enforcer[/card] costing two less for -1/-1 or a 5/5 5-drop with conditional [card]Hellfire[/card]. Any way you slice it it sounds good.

Doesn't feel great for Constructed or Wild. Seems playable in Arena, where the reward of a flexible 6 damage for 3 mana might just be good enough reward for 1 mana do nothing. We'll see...

Too slow for Face Hunter, too weak for Deathrattle Hunter. Looks like dusting material unless there is a way to stack a lot of hero powers. It doesn't even seem decent for Arena.

Looks good with [card]Springpaw[/card] or [card]Desert Spear[/card]. In any event it seems better than [card]Toxic Reinforcements[/card], which is admittedly not saying much.

Feels strong in Arena for the high health, constant value generation, and relative rarity of removal. In Constructed or Wild, it feels like by the time you play it your opponent should be able to deal with it. But if …

Like [card]Curious Glimmerroot[/card] obviously, with the bonus of some intel about what is in your opponent's hand. Looks useful.

First 12 win deck:

Pretty aggro deck. MVPs include [card]Avenge[/card], [card]Vinecleaver[/card], [card]Keeper of Uldaman[/card], [card]Spikeridged Steed[/card], and 2 [card]Fire Plume Phoenix[/card]es. Also, in this rotation [card]Hydrologist[/card] is pretty sick; there seems to be only three available secrets so …

Won as Hunter, and got this from one of the quest packs:

[card]BEEEES!!![/card], just because it will be fun to say when you play the card

For me it is Mercenaries 280, all day, every day.
