Trust me, Mate, I think this is anything but. I'm partway a back seat player now considering I rarely go on the game, but in my opinion, the last many expansion at this point have been an infinite and unrestrained loop of powercreeping that has really been harmful to the game, and this card, while not best, does indeed embody that to a terrifying degree.
Their power creep comes in two ways, raw power, as in cards that really just straight up are so magnanimously better than old ones its crazy, and all that even when they don't get lucky on their RNG elements.
This one instead is crazy based on its RNG element. Yes, you might not draw it, and then it'll be a fair card as a 3/4 for 3 as you stated yourself. However, if you draw the added card on the next turn after you play it, it is insane. And if you draw it on any turn after you played it, it is still insane. So yeah, I very much agree with ya, that card is bonkers, and sadly that is a big norm for both RNG cards now. Makes the game to watch with all of the chaos, but makes it feel so horrible to actually play it, sadly.
6/14 over 2 bodies with a deal 3 damage to opponent's face for 3 is not reasonable regardless of when you draw it.
Side note, that damage of 3 can be more if you have any attack buffs on the field. Also, we don't know how they've wired him, so that attack might give him a charge, which might mean you can use windfury on him to get a bonus free charge effect on him and immediately make the second attack. Or, alternatively, giving him charge might not let him attack because he already had charge. Just a thing to consider, considering Blizzard's inconsistent coding. :D
