This deck is reveolved around filling your opponent's hand with useless cards such as rocks, hammed unit and the 6 cost unit from Baron.
There are a couple of core cards here:
Korg/Rockslide- these two go hand in hand with what we want to do, buff our Darkhawk while also having our opponent keep rocks in their hand since they won't play them most of the time.
Beast- Beast helps us by bouncing back our small units such as Korg, Mold, Baron etc. He helps us keep pushing our opponent to have useless cards in their hand/deck thus making our Ronan and Darkhawk a lot more consistent.
Mystique- we use Mystique mainly to copy either our Ronan or Darkhawk, That way even if our opponent tries to threaten us with a Shang Chi/Enchatress we still have a way to benefit (if we have priority).
Darkhawk/Ronan- while these two seem to be the polar oppisites in terms of their effects they can actually work really well in this deck since we have way to prevent our opponent to draw and we can fill their hand with cards they don't want to play.
