The Darkglare shell extremely compliments this deck so you can draw your deck quickly and consistently. I went 30-11 with this particular list, however this deck is definitely not optimized as it is a new archetype. Although, I believe this deck has Tier 1 potential.
This deck is pretty interesting because you have a 10 mana, 4 card combo that deals 60 damage guaranteed. (Wretched Tiller, Deathspeaker Tiller, Deathspeaker the other Deathspeaker, into Hysteria on the Tiller) which causes Tiller to attack 30 times (that is the infinite loop limit cap), causing the 60 damage.
There can be some interesting lethal puzzles that can be possible, because if there is 15 hp of minions on the field, you can OTK your opponent with a 7 mana, 3 card combo, Wretched Tiller into Deathspeaker, Hysteria the Tiller. Fun fact, Deathspeaker gives you 4 more hp, so really your opponent just needs to give you 11 hp to work with.
Last tip I'll suggest is using Dirty Rat to help force a board from your opponent so you can use the 3 card OTK. Emperor really helps us make even more versatile OTKs. It's best to just throw him down on Turn 6 if you have combo pieces in hand. Hitting 1 or 2 combo pieces jumpstarts your win rate.
