Disclaimer: This deck will only be successful in a board-centric Standard meta.

Inspired by the new spell Prescience this deck aims to summon deathrattle minions that cost 5 or more, most of which are the new undead minions. With Prince Renathal as the only minion that costs less than 5, Prescience is guaranteed to spawn at least 1 taunt minion to help stabilize the board. 

Masked Reveler will help cheat out sticky minions like Harkener of Dread, Blightblood Berserker, and Flesh Behemoth (the 3 best outcomes), Bog Beast, and Taelan Fordring

There are a total of 6 other undead with Taunt in addition to Flesh Behemoth, so there should be a high likelihood of getting the full benefit of this deathrattle effect. The weakest of these minions is Shatterskin Gargoyle, and can be removed if the redundancy is not needed.

From De Other Side is both a tool to get your deathrattle minions out, but also benefits greatly from Sire Denathrius to gain 10 HP + clear a minion + Infuse the real Denathrius still in hand. 

Famished Fool has anti-synergy with some of the deck's game plans, but is necessary to mitigate Shaman's weak card draw. If including Famished Fool is deemed too detrimental, Far Sight could be a decent replacement for early discounts on the bigger minions in this deck. Some play testing will be needed
