This deck usually overvalues low curve fast aggro decks by reloading and efficient removal or healing
For any other matches, the win condition is self fatiguing after playing Complete the Ritual's reward Blightborn Tamsin

The Demon Seed and Establish the Link reward (deal *3* lifesteal to the enemy hero) can be either manipulated with Talented Arcanist to deal and heal *5* damage, or played along Crooked Cook to draw an extra card along Life Tap, This will be refered as "Empowered Reward"

Talented Arcanist´s Battlecry, along with Nagalings (not in the deck) will not be consumed by an "Empowered Reward" until after you cast a spell, the best options to use this interaction are
Play Talented Arcanist, Life Tap (which triggers "Empowered Reward") and then play Grimoire of Sacrifice for *4* or Drain Soul for *5*
OR
Play Talented Arcanist, and Hellfire for *5*

If your Doomsayer triggers, playing either Imp Swarm (Rank 1) (especially Rank 2+), Shadowblade Slinger or Blood Shard Bristleback on an empty board can be fine, and even required in some scenarios

This deck is VERY low curve, so you are expected to draw mostly through your hero power, and use Impending Catastrophe and Scourge Supplies to reload your hand when it eventually empties by turn 8-10

Twisting Nether (and Gigafin) is a resource that can help you reach safely to the last two taps of your Complete the Ritual, or stall a couple turns after completing it to have enough damage in hand to burst your opponent.

At late game, once all you need is to play Blightborn Tamsin to win, you will need to have saved some card draw to win, as said above, Twisting Nether (and Gigafin) does act like a card draw in most scenarios, but having a way to draw enough to OTK is important

It will probably take some games to get the flow of the deck, but it's very rewarding to do so and plan ahead with the current information

GLHF!
