Those are not at all similar situations. You can play BGH as a 4/2 for three mana, you can play TBK as a six-mana Yeti. The entire point of Zoo is to flood the blood with cheap, efficient minions so you
can't play Hellfire at all unless you're on the ropes against another aggro deck (particularly the mirror), a position you're more likely to avoid in the first place if you had something like DID, Argent Commander, or whatever instead of Hellfire. ;[ If Hellfire even helps you in the first place, since it deals damage to your face (in a class that cannibalizes itself for draw) and leaves you four mana down to repopulate the board compared to your opponent's next turn. It's not that useful against slower decks either like Handlock, Paladin control, taunt-heavy Ramp Druid except as a very bad form of reach since they play few, large minions that Hellfire won't kill on its own.
It's kinda like BGH in specifically Handlock, which is unplayable when the only 7+ attack minion on the board is your own because the battlecry isn't optional and can target your field, except Zoo always has "the only 7+ attack minions on the board." And BGH is already pretty dumb in Handlock (on the ladder, not tourney play). Hellfire in Zoo isn't a situational card you can play suboptimally anytime, it's a situational card you can't play at all most of the time.
And not that Azure Drake is bad but in a Zoo deck? Very strange. Its body is underpowered for its mana cost and you can already emulate the draw with Life Tap. I've never a seen Zoo deck run Yeti and even DID is in a minority of them. Zoo's not really about card efficiency. I've seen plenty of even goofier shit that I've lost in my IRC ramblings though, I just made that post to stop myself from rambling further.
Three games today, three wins... killing a total of three minions according to my quest heh. 417 Legend. Darn, so close to 420. also I just realized yesterday I'm basically playing shockadin fuck (I guess it's a decent deck after all but at least I pride myself on doing more than just mindlessly throwing Charge minions at my opponent's face. Anyway, Level 60 now so time to play something else I suppose?)
edit: I decayed three ranks already, aww yiss
