Yes you have a nice workaround here if you don't own specific cards. To the Loatheb discussion: I personally think its more of a card that fits the aggro deck. You slam it and win this exact turn because you locked your opponent out for the next turn, hence he cant clear your board. In a control match up it doesnt really matter most of the time if I do my combo now or next turn.
VS APM Mage you want Cult Neophyte because it is cheaper and way faster (I died turn 4 more often than I would like.
So bottom line is that its not the best card in the current meta in a control deck. (Too slow/bad stats)
