The best way to use Rhok'delar imo is combining it with Hemet and simply shitting out all the early game minions then flushing them out of your deck for the DK and Rhok'delar. I've been contemplating running the quest to fill the deck with raptors to stall fatigue and allow for pressure options but other options might be including purposely bad 2/1 raptor hatchlings.
This is what I'm currently thinking but I'm a pretty amateur deck builder and would love some advise with Hemet style Rhok'delar control hunter builds. I want to fit tracking in but I'm afraid of having to dump either DK rexxar and Hemet in the same go, it halts a lot of combo potentials even if it allows faster access to DK rexxar *Edit* Contemplating between candleshot and Eaglehorn, I feel the life saved and mana reduction make candle shot too good to exclude.
The deck is fine, but most of the time you won't finish the Q before drawing both Hemet and Rok'delar. Also, finishing hunter quest is not a reliable win condition, you spend too much deck space and resources on little reward.
Lastly, using Rok'Delar on empty hand is still pretty weak win condition, as it will fill your hand with secrets and Crushing Walls.
But the deck looks innovative and nice spin on the no minions hunter deck, might be fun on lower ranks.
EDIT: You can't run control hunter without Deadly Shot, your deck doesn't have enough removal, and switch one Flare for Tracking, perhaps both.
