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.
Always set Jowls of Dark Demise face-down, when flipped face-up you can take control of one of your opponent's monsters. When flipped face-up during your opponent's battle phase you can take control of their strongest monster on the field to protect yourself from other attacks during that turn.
By banishing Fiend-Type monsters in your graveyard, you can special summon Dark Necrofear from your hand. It has a decent attack and very high defense. When this card is destroyed by your opponent by any means, you can take control of 1 of your opponents monster by equipping this card to it.
By having Archfiend Palabyrinth on the field, the attack of all Fiend-Type monsters that you control will increase by 500.
Trance Archfiend can increase its attack up to 2500 by using its own effect and by having Archfiend Palabyrinth on the field. It can increase its attack by discarding a Fiend-Type monster from your hand. Later on, you will use those discarded Fiend-Type monsters to special summon Dark Necrofear.
Besides from increasing the attack of all Fiend-Type monsters that you control, Archfiend Palabyrinth has another effect that lets you special summon an Archfiend monster. Target Archfiend Empress on the field, then banish another Fiend-Type monster you control to special summon another Archfiend Empress from your hand, deck or graveyard.
I like this deck very much after i see it from silentfold. But i have a problem here. That skill fiend farewell doesn't drop for me. I have farm hours 5k gate key to farm rex40,wevil40,yugi40
no it cannot lol. there's a reason why there are hardly any decks that run 3x mirror wall. no need to bitch about it my dude. saying a deck is only viable because 3x mw is just an excuse you make for others having success with a deck while you cant make it out of rookie 2. i wish u the best of luck and i hope u can manage to win a few games to get to bronze
Escape from dark dimension is essential in this deck, you need at least 2 to summon archfiend empress, if you don't have any I suggest replacing the high level monster because it will be a dead draw, and focusing on necrofear instead.
