A joke.

I wonder if this would be good enough to make odd hunter a thing in wild...

Steamwheedle sniper never saw any play because it overvalued the mechanic. Same with every spell damage card for mage before boomsday. Once they started valuing the price of the mechanic appropriately it became viable.

Now that they're making hero power use a hunter mechanic they have a chance to try and value it more appropriately to incentivize people to actually use it since steamwheedle sniper was useless.

Recycling a mechanic? Maybe, but if it actually sees play this time around it'll be different.

1 mana 1/3 is ridiculous. This card would still be insane at 1 mana 1/2 or even 1/1. Sometimes you have to wonder if Blizzard even knows wtf they are doing.

I don't think it is this oppresive how you talk. This card is 1/3 stats for one mana, witch is very good, but deal 2 dmg to target minion for 2 mana is not really amazing effect. This card is more value then tempo. So 1/3 is pretty ok on this one. (1/2 would be probably ideal in power terms, but be truthfull, would you play this card as 1/2 or almost any other 1drop from hunter?)

Remember how oppressive Steamwheedle Sniper was? Exactly.

biz is seriously running out of ideas

Steamwheedle Sniper, but better!

10x dust cheaper

Pretty much. Loses only 1 attack to be 1 mana cheaper (and we all know 1/3 for 1 is a great statline), and an extremely useful ability for any deck that isn't aggro or tempo (so midrange or some sort of control/combo hunter).

So how come this one is common and the old one was epic ?
I'm really wondering how a card's rarity is decided ...

Well pretty simple, at the time when it was an epic it had a unique effect(flavor), now it is not unique because of the epic one so it kinda became a common this one. Blizzard logic?
