If you already have two of the 2/2's on the board it's do-able.

Voted Bad. Refreshing your hero power is useless on turn 3.

I'd say, that this is a worse garrison commander with +1/+1 stats and it can only be used this turn

So that garrison commander wasnt used, I dont think this will see constructed play, because a second even if upgraded hero power is just too slow to be played.

In arena this card as a common is actually pretty solid, because it is a 3mana 3/4, which is already good stats with an additional effect, gaining some value if needed.

Considering how Garrison Commander see no play in Wild and is arguably a better card, I don't expect this to fare any better. The only deck I could see it used for is in Quest Warrior, since it has good synergy with both upgraded base hero power and Die Insect. On the other hand it's not a taunt, so you sacrifice consistency in your quest completion.

Above average arena card, may see play in a meme quest warrior I suppose, it can't keep OTK paladin alive since you can't have over 10 mana Kappa. I like the idea of refreshing your hero power with basically any DK already played, but I'm not sure if this is good enough, similarly for Clockwork Automaton.
