The idea is to discard
Haunted Dead,
Stitchwing Skaab,
Prized Amalgam
, and
Eternal Scourge + Scrapheap Scrounger
by looting with
Cathartic Reunion/
Tormenting Voice,
Cryptbreaker,
Insolent Neonate, and
Wharf Infiltrator (or by reanimating Dead or Skaab). When you discard to reanimate your zombies, or when you exile
Eternal Scourge to return
Scrapheap Scrounger,
Prized Amalgam
comes back for free. And then you can cast Scourge from exile, let it die, exile it to reanimate Scrounger, cast it, ad nauseum.
As a bonus, we can mill 2 cards for free each turn with Perpetual Timepiece, then we can exile it for 2 mana to shuffle our removal back into our deck. It is perfect in this deck, though it is a win-more flex slot. Fevered Visions will help refill our hand for more discarding, and it can win games by itself against control.
Voldaren Pariah
can also wipe away the opponent's creatures; the activation cost of sacrificing three creatures isn't very bad when they all come back nearly for free. I put only 1 in the main deck because sacrificing 9 power to gain 3 can slow us down quite a lot, but it can help get rid of some annoying blockers.
Since most of what we are doing has nothing to do with casting spells once we get started, there is almost nothing control players can do to interact with it other than returning creatures to our hand with Engulf the Shore and Thing in the Ice
. But we have removal to kill an unflipped TiTi, we can comfortably chump block an Awoken Horror, and we can just discard all the stuff from our hand again anyway, so we can always bounce back. The only way to deal with this deck is with exile-based removal or racing with aggro, and the sideboard has answers to both.
