The Greatest Dinomancer
Here I show off the fun combo from the Hearthstone Journey to Un'Goro set using Spirit Singer Umbra and the Cruel Dinomancer.
The combo requires you to have discarded ONLY a Cruel Dinomancer, and summon Umbra and Dinomancer together in the same turn. I use Hemet, Jungle Hunter to thin the deck to get to the combo.
NOTE: This is a TERRIBLE deck, it won't win many games because it's just Zoo with a combo tagged on it!
