I originally had 4 copies of Alhed, but I've cut him down to 2 instead so I can have more units that cost 3 to smooth out the early game. Alhed is the least essential of the 5 cost units and basically a win more card. I have Copper Conduit currently on the sideboard. If I find aggro to be a prevalent I might remove Alhed completely and replace with Conduit or cheap removal. Only thing to beware of with Conduit, like Pyroknight, is that it will be removed by Trail Scourge's summon ability.
