Well to be fair, your opponent would have to know to silence both Undatakah and Shudderwock to completely screw you over.
You could always run 1 Baleful Banker and play Undatakah + Baleful Banker on turn 10 to be safe.
It's just a deck I mess around with in casual. I didn't make this to climb on ladder, lol. And it does a fine job of beating aggro and mid-rangey decks like Murloc Shaman and there is enough healing to beat bomb warrior.
