Well, it's basically a Boulderfist Ogre which provides armor in case you want to facetank something with Sul'thraze or Gorehowl. And if the new quest has been completed you might also summon multiple 4/3s for just 2 mana each. Yeah, it's just a wet dream but Tempo Warrior seems to be on the verge of becoming a very competitive deck.
I’m a warrior main with a Baku control armor deck and a sort of mech deck. I have dr boom in it and usually end up having 40 armor on turn 8 and this card is gonna be perfect for my deck! Thank you blizzard!!!
I can see this being used across many Warrior decks as it can be flexible, but mainly I think it is introduced to support Hack the System and before that Sul'thraze. With that being said, I think Warrior players will eventually stick with Control and Bomb variants, as this archetype and taunt seem for the next rotation.
