I appreciate that the card makes direct reference to Alex, given how prevalent she is in Control Warrior.
Beyond that, however, this doesn't really fit in any given Warrior archetype. Perhaps midrange Dragon Warrior will become a thing in TGT, but right now this card doesn't really fit. Control Dragon Warrior already exists, and it doesn't need more early removal.
In arena this card will be a good buff for Warriors. Right now they have no consistent rares, and the potential for a 3/3 with Charge on turn 2 will be very good, and a 2/3 is still acceptable.
