I'm just not seeing it. Yes there is an obvious fit with Dark Pharaoh Tekahn, but will that deck be any good? You have to Draw Tekahn or the deck is trash. But my biggest issue is with how slow it is. Its a value card for lackeys; which are tempo cards. Its a measly 4 mana 2/3 (weak) and to really get the value out of it you would need to play it on turn 7 or later. I'm sorry but by turn 7 I want do do more than play a 2/3 and 3 1/1s that give me small temp bumps or some random spells/dragons. I'm probably wrong but I don't think this card is that good. If it was a 3/5 maybe, but then its still slow- I just don't see it being worth the value.
What you have to realize is the reason for its insanity is you need only play one 1 mana card and this card generates 6+ cards. And you call the lackeys "measely," but they be great effects and generate great tempo gain.
This is not being overhyped imo, it's going to be very strong. It needs only a single lackey to get going and then you're just doing lots and lots of stuff while generating a ton of value.
This is almost like gadgetzan on 4 mana that generates far more tempo. The only downside is, as some have stated, is that 4 classes pretty much can't play this. The heroes better get some big love.
Edit: Also, imagine rogue going into turn 10 with this and spirit of the shark loaded. If you think that turn ain't gonna be crazy, you crazy.
The problem is you have to have a lot of mana for this card to be any good. It's just not as crazy as people make it out to be.
