Inspired by this deck by user watermelon86.
Instead of going full-on card draw, this deck is going the healing route,
while also keeping some decent cards for cycling.
Also sprinkled with tech vs secrets because oh so many mages/hunters/never surrender.

The combo rotates around these three cards.

The goal of the deck is to use Expired Merchant while having Cruel Dinomancer on-hand.
Discarded Cruel Dinomancer makes your next Cruel Dinomancer behaving like the original Dreadsteed, practically unkillable unless silenced

Spiritsinger Umbra is there to help you fill your board with undead Dinomancers.

This strategy is hard countered by Mass Dispel, Devolve, Plague of Murlocs, unconventional board clears like Vanish or Psychic Scream, and also of course bad draws.
