The main combo pieces: Myra's Unstable Element, Leeroy Jenkins, 2xPreparation or Shadowstep+Preparation, Cold Blood, Shadow of Death and Shiv.

After you have all of these in your hand, use Myra's Unstable Element and next turn the rest of the pieces.

If you can hit any piece (except Preparation of course) with Wondrous Wand from Togwaggle, then its GG. :D
