I think having early minions to play like this 2 drop or the 3/4 3 drop can work well even in a pure control deck, you're gonna hero power face for 0 and emote on turn 2 most of the time anyway, might as well play a good minion.In a pure control deck it doesn't necessarily work that well. If priest still gets overrun in the early game, then yeah this guy will help. If not, then a value-drop like Curator is better.
obviously if you run N'Zoth, Curator is better. if you don't, you probably need the board presence more, or just the threat of a 2 mana minion which forces the opponent to have removal before the board gets filled with 2/2s.
