Set Doomdog Octhros and let your opponent destroy it. Once it goes to the graveyard, you can pick either Dark Necrofear or Invader of Darkness from your deck to be added to your hand. You can then use Fiend Farewell skill on your turn to send a Fiend-Type monster from your deck to your graveyard, which you will use later to summon Dark Necrofear.
Summon Invader of Darkness as soon as possible, as he is probably the most important monster in this deck. Invader of Darkness is a 2900 attack beater, and more importantly while he is face-up on the field your opponent cannot activate quick-play spells. Use Stray Lambs and use the tokens as tribute to set Invader of Darkness, which would be safe from most attacks with his 2500 defense, then flip him face-up your next turn. You could also flip a Jowls of Dark Demise you set the turn before to take one of your opponent's monsters, then use Jowls of Dark Demise and the controlled monster to tribute into Invader of Darkness.
