Message of Death

There are 3 ways to win with this deck, first is with Destiny Board's effeck, the second is using Curse Necrofear & Dark Necrofear's effects to give you the advantage over the opponent, the last is to have the opponent burn themselves with Dark Sanctuary if they can't remove it. First step is to get Curse Necrofear into the graveyard, there are multiple ways to do this:

1. Summon Tour Guide From the Underworld & use her effect to summon Fiendish Rhino Warrior, go into Link or XYZ play & send Fiendish Rhino Warrior to the graveyard & use his effeck to send Curse Necrofear to the graveyard, you can also send one of the Drak Spirit's there if you use Cherubini.

2. Use Foolish Burial to send Fiendish Rhino Warrior the the graveyard & then use his effect to send Curse Necrofear there.

3. Use Trade in to send Curse Necrofear to the graveyard.

Dark Sanctuary & Battle Fader are the deck's stall cards, after you summon Battle Fader, if you have Destiny Board/Spirit Message's & Sentence of Doom set up, get rid of it & use Sentance of Doom's effect to return it. Terraforming & Metaverse will help you get it.

Even if Destiny Board gets destroyed you can use Dark Spirit's Mastery's graveyard effect to send them back to the Deck & draw more cards potentially going +4 also & it's probably better your opponent waste's their resources trying to stop Destiny Board, it you do manage to get Destiny Board & 3 of the other Spirit messages use Sentence of Doom to place the last one & win the Duel.

Finally there's Curse Necrofear & Dark Necrofear, use the Dark Spirits effects to summon Curse Necrofear from the graveyard & preferably get it destroyed if you have face up spell & trap cards at the end of the turn it will return potentially destroy up to 5 of the opponents cards. Dark Necrofear needs to be summoned properly first by banishing 3 fiend type monsters, but you should have no trouble getting fiend type monsters into the graveyard & you can use Sentence of Doom or Curse Necrofear summoning condition to retrieve them. if both of them get destroyed on the same you can take control of on of the opponent's monsters and destroy a card on their field since Dark Necrofear counts as a spell when equipped to an opponent's monster. When either of them get destroyed use the Dark Spirit's graveyard effects to add the to your hand allowing you to summon them again.
