    Strange enough, the puzzle I’ve struggled the most with is the 4th puzzle in survival (hours – LOL go me!). Then proceeded to get the card back after spending 15 min with the last two. Quite a bummer since the very last puzzle (survival 6/6) was by far the easiest compared to the last ones of kill, board clear and mirror.

    The last mirror puzzle was the best in the way it exploits Hearthstone mechanics. Not rocket science (which is also not an exact science), but I completely loved it.

    For those still stuck on the 4/4 clear board of Dr Boom :
    1 – demonfire on ultrasaur
    2 – Moat lurker on the left side of the board and eat the pyro
    3 – play arcane anomaly on the right side of the board
    4 – demonfire the jade golem
    5 – ratcatcher on the ride side of the board and eat fearsome doomguard
    6 – bloodfury potion the ratcatcher
    7 – void terror on the lefty side of the board to eat only the moat lurker
    8 – defile, enjoy

      always 3 minions left … am I retarded or whaaaat lmao

      August 22, 2018 at 9:06 pm

      There is interesting fact that stormwind champion buff doesnt go off while defile in process although green “attack” numbers become white (as if the other DR BOOM`s minions ARE unbuffed).

      As it appeared understanding of this is a key to finding a solution on your own =)

      • Tyrii
        September 4, 2018 at 2:22 am

        Can anyone verify this? I’m not sure what you mean by finding a solution on your own. Did you find another solution?

        Whether attack stays the same or doesn’t, cannot affect the puzzle during defile. It can only affect the puzzle before playing defile and in this case the attack definitely changes when SC dies.

        No solution I’ve come across exploits SCs ability in terms of HP – a minion resurrects on Dr. Boom’s side before SC dies, as opposed to after he dies.

      August 21, 2018 at 4:53 pm

      Almsot there, Basically you want to get a cascade going still trying to find the right combo. so each minion on the board has one more health than the last in sequence. Best way so far is to lurker the pyromancer but im not sure what else yet.

    I did erratic explosive in a completely different way: Pyro, Tentacle it, defile, refresh (bomb on 6 on your side, pyro with 4 health); spider, hero power, divine spirit the dude, then defile. This empties the board but for the bomb, which is at 1 health on their side: kill it with holy smite.
