You can do board wipes but since this usually uses all your crystals you have just stopped the existing damage and they are going to play 2 minions next turn. Which leaves you behind again.
A lack of good blockers that can actually 2 for 1 are rare. Taz and druid of the claw seem to be the only ones that might have a chance. Taz usually gets one shotted by a seargent pump or eaten by the no discard Doomguard. or paying for double molten core protector but then still i have been foiled by a silence and power overwhelming on the other
So tell me how are you supposed to turn the tables and live while your at it.
I mean i had this game playing my paly the other day I went second I found the game rather hillarious given my opening hand was 2 concerates and an abom
Turn 3 Concecrate killed 3
turn 4 concecrate killed 2
turn 5 abom got souled
turn 6 avenging wrath
turn 7 protector of the king
turn 8 tyrion
Other card games have accounted that rush was supposed to stall out.. in hearthstone it never stalls.. you can never hurt your opponent because nothing is out there alive for you to hurt your opponent with just letting them lifetap without any risk.
A huge reason is there is complete lack of 2/4 drops for 3. All the 3 drops can be killed by a 2 drop for the most part .
So tell me how are you realisticly supposed to turn the tables on them without basicly luck drawing the limited AoES?
