Let’s look at some ‘iconic’ cards with good stats for their cost:
Chillwind Yeti, 4 mana, 4-5
Boulderfist Ogre, 6 mana, 6-7
That Worgen Greaser, though… 4 mana, 6-5. What?
It might be suprising the community didn’t vote for its inclusion in the Core Set [1]. Perhaps that minion would be too ‘overpowered’ and a new ‘meta tyrant’?

Bro, are you OK? xD
Hahahahahahhahah BRO
Are you mocking the DH haters? Because of shopper being 6/5?
You do realize it’s 6/5 with discover a minion, discount it and get a 1/1 which does the same?
That’s far from Worgen Greaser.
And it’s discover a minion in a comically small Demon pool
A 1-mana 1-1 is weaker than a Snowflipper Penguin, by the way. 
1/1 which discovers a demon doing something, however, isn’t
What could SHOULD have been a colossal:

Such a missed opportunity!
Yeah, neglected to mention it last time: for 1 mana, that’s essentially a sligtly upgraded lackey (and the only thing you’d really want with those stats is Magtheridon, which isn’t even guaranteed; maybe also a situational Eye of Shadow, but that’s about it; PS oh, yeah, the secret guy, of course, good for 1 mana, forgot about it).
