bliz released this expansion with low power level, due to reasons! and decided to toss a card too crazy to spice up the meta then nerf it a couple of weeks in so we will have some sort of change, and when we do have a powerful card nerf we get a new meta, with the new meta HS will feel fresh again and people will get excited.
this is not a control card, this is more of a tempo/midrange card. In today's standards tempo and midrange have no chance against the meta, they get beaten out real quick by aggro or out valued by control.
the archetype need more support and this looks really promising tho.
