First Shot Explanation
I have been playing against a lot of Brachiosaurus decks recently, which is part of the reason why I wanted to make a board clear heavy deck. (I also wanted another Evil based deck.)
To compliment the board clears, I added the Reapers, Murderous Necromancers, Medusas, and Necromancer Lords. All of these are incredibly powerful champions that are either removal or need to be removed. Medusa can be played off-turn, and all the rest will control the game if left alive. I did not include Dark Assassin because it is too easy to remove with a single 0-cost card.
Soul Hunter is included almost exclusively to be played when one of my Reapers is already in play. In that situation, I can use Reaper‘s ally ability to target Soul Hunter. This breaks the Soul Hunter dealing 5 damage to my opponent, puts a demon token into play for me, and put the Soul Hunter in the discard pile to come back on my turn. Reaper will also trigger its ally effect whenever you use a 1-cost Evil event to draw 2 cards. This does not work with 0-cost Evil events due to the nature of ally triggers.
The Ancient Chants and Lesson Learneds are included primarily for the 4 card draw combo, explained at Epic Insights. Lesson Learned also has a lot of other strong events to copy such as Surprise Attack, Final Task, Ceasefire, or any of the board clears.
Surprise Attack and Final Task can provide me with more fast removal. One of the best targets for this is an Angel of Death for an off-turn board clear.
3 Arcane Researches are included for a variety of reasons outlined by Derik M in an earlier comment.
Unquenchable Thirst can clash a bit with Arcane Research. I am not sure if I want both, or I might just adjust the quantities of each.
Plentiful Deads are included primarily for fast chump blockers.
Since this is a control deck and I have the Arcane Researches, I might add in some more singletons like Lightning Storm and Lash.
I avoided some strong non-Evil cards like Brave Squire and additional Flash Fires because I wanted to keep my ratio of 1-cost Evil cards high. It would be nice to cut the Sage and Good 1-cost cards altogether, but the 0-cost cards I gain from them are quite nice. If I were to cut them, it would help my Reapers, Spawning Demons, and Plentiful Deads. It would also be more incentive to add Infernal Gatekeepers.
The main reason I labeled this highly experimental, aside from heavy board clears, is the card draw situation. Most of the slow or 0-cost cards included do not draw cards. In addition, the board clears don’t draw cards when I use them for their “if it is your turn” effect. Due to this, I included the Ancient Chant/Lesson Learned combo and the Cease Fires. I might have gone a bit overboard though, since this deck only has 9 zeros that don’t replace themselves or come back to hand.
