Well cool I had just posted a big explanation of Noggenfogger's lore without refreshing the page. Never mind then

Quote from Kovachut >>

Charged Hammer?

 That's the one! 

A slow burning smacker (A weapon with many charges)
Seldom seen, how tragic (It never saw any competitive play)
That elements could not match (It's a shaman card)
The Mooneater's magic (The hero power it gives you is the same as the upgraded mage hero power)

On to you

all very clever answers, maybe my riddle was too vague. Time for another clue

When my power be spent
Or have drawn oozing ire
My lightning shall smite
My master's desire

Hopefully that makes things a bit easier, but still not too obvious

Clever reasoning, but not what I'm looking for. You were sort of close on one point.

Alright, here y'all go:

A slow burning smacker
Seldom seen, how tragic
That elements could not match
The Mooneater's magic

Holy shit I think I just got it:

is it Call in the Finishers?

It's the same as Fiendish Circle,which is from Witchwood and summons demons instead of murlocs

I feel like there is literally nothing this could be. There are only three demons from the Witchwood (Felsoul Inquisitor, Witchwood Piper, and Witchwood Imp) and of those three, there is not a single minion that shares their exact costs and stats AND whose text is only one word off, and I've looked over every single minion in the entire game. Unless that is, you're talking about an uncollectible minion from an adventure, which I haven't looked at

Perhaps Twilight Drake? Its Witchwood counterpart being Bewitched Guardian

Is there a reason not to run Prince Liam? I feel like he would suit the deck well

The reason you can't attack the curator with a rush minion is because that isn't how fucking rush works. It doesn't matter if the enemy hero has taunt, rush minions can't attack heroes the turn they're played

Decided to go for something that would synergize with other elementals as well. 

Next: A card that enables a 4+ card OTK combo that doesn't already exist.

HotS recently had a bunch of their developers moved to other projects, and there won't be any more officially sponsored tournaments for it, so with that Blizzard has essentially acknowledged that it's a dying game

Next: A minion with a symmetrical Start of Game effect (equal benefit/detriment to both players)

ITT - OP can't take criticism

ITT: People can't read, and read Deathrattle as Battlecry

(Don't worry, I did too)
