Hearthpwn

I'm doing a deck with Emeriss and The Curator for a particular combo.
I would like to know which strategy is better for draw cards or cycle the deck.

In wild.

could thin your deck with secrets plus subject 9 and phase stalker maybe throw in diving gryphon with some rush cards. thats like the only draw packages i can think of right now other than your basic loot horder/novice engineer. 

Tracking will help you find combo pieces. There is a risk of losing one combo piece to find another, but it's much smaller than the risk of never finding what you need if you don't use Tracking.

Big secret package with Subject 9 and 2 Phase Stalker w/

2 Tracking

2 Diving Gryphon + rush minions

1 Hemet, Jungle Hunter unless that screws up your combo, if you need small stuff for your combo try 2 Tol'vir Warden

2 King's Elekk (again depends on you combo)

You could also make some Ursatron, Runic Egg, Arena Treasure Chest+Terrorscale Stalker+Play Dead+Feign Death shenanigans.

Then there are nerfed classics like Starving Buzzard+Unleash the Hounds

You could also have a spell heavy deck and Stitched Tracker, Master's Call the minions

Without knowing what your combo is, Tracking, Cold Light Oracle, Stitched Tracker
