The point of the deck? A lot of exhaustion and then KO'ing. (so, when making changes, please stick to this idea of exhausting/KO'ing, please)

While using Sadistic Choice to help KO'ing or hand control.

Either way, I see Sadistic Choice to be a very strong card.

Remove a threat from the field, or two potential threats from their hand.

Rhino? Just for some muscle, I guess.

With no tutor and only Osborn Industries to help I think that you should put more characters in. A second Hush and a Killer Croc sound good.

Also, with this much exhaustion you could/should put in Crushing Blow and/or Sucker Punch. 4 NML and 4 Belfrys are overkill. I suggest 6-7 total between both.

Finally, 8 KO PTs and no way to stun while on defence is not good. Try some Nasty Surprise or, better yet, No Fear.

Made some changes.

i want to try and suggest a diffrent route if i may why not go wennie and use firefly instead of harvey dent

syndacite has some of the best and most aggro oriented lower drops eg tomestone, baslisk and rhino why not take advantage of this

certainly plat no fears or nasty surprise and maybe even a salvo to give range again im going to agree and say where are the sucker puches agian your creature to plot twist / location
ratio is 1:1
sadistic choice is a great card and good choice on running 4

but you really do need to beef up on your creature count
good luck and happy gameing
