Pretty sick deck once you get the combo running.
The goal is to discard one Cruel Dinomancer, then all you have to do is play another Cruel Dinomancer on the right of Dorothee, and you have unlimited tauntage. You may also play the last one on the left, so that you have a repeatable charge minion as long as you can sacrifice it.
Be careful to absolutely not discard the Darkshire Librarian, otherwise there is no way you will set the combo off.
Forbidden Ritual and Feeding Time help providing taunts while you assemble the combo, while discarding them isn't an issue.
Mortal Coil, Life Tap and Darkshire Librarian all let you draw cards, but usually you want to try to empty your hand at the beginning so that you can guarantee a Cruel Dinomancer discard, with the help of Soulfire or Darkshire Librarian. I find that with only Soulfire, it's quite hard to discard it.
Defile, Drain Soul and Hellfire can all help you try and stabilize the early- through mid-game.
Finally, Bloodreaver Gul'dan lets you heal and ping in the late game, since Cruel Dinomancer with taunt will not block spells, though it's not essential since most people will be playing minions almost exclusively.
The only essential card is Cruel Dinomancer, I guess.
- Darkshire Librarian can be replaced by any discard card, although be careful, playing additional minions will increase the chance to fuck the combo up.
- All other cards may be replaced by any spell, you'd probably want to play cards such as Corruption, Corrupting Mist, Demonfire, Drain Life, Shadow Bolt, or even Kara Kazham! for protection.
