Ok, well I recently applied to be a member of the Lair of Dark Monarchs. And got turned down (BOO!!!!). However, the nice Dark Monarchs (misnomer?) decided to take the time to tell my what it is that they didn't like about me (Cool!). And, to put it simply, my deck building just isn't up to par, and I am too new at the game. So if I practive Fiendish deck building for 6 months or so, I could kill two birds with one stone, and get in the club, right? Well, in theory. So here goes: (keep in mind this is a very rough draft)
7 (yes, 7)
Dark Necrofear x2
Lava Golem x2
Invader of Darkness
Berserk Dragon x2
11
Archfiend Soldier x2
Shadowknight Archfiend x2
Wall of Illusion x3
Cyber Archfiend (new)
Sangan
Terrorking Archfiend x2 (new)
17
The Puppet Magic of Dark Ruler x3
A Deal with Dark Ruler x2
Reload x2
Dimension Fusion x2
Scapegoat
Heavy Storm
Giant Trunade
Emergency Provisions (new)
Nobleman of Crossout
Snatch Steal
Mind Control x2(new)
5
Archfiend's Roar x3 (the monster can't be tributed, but it still works for The Puppet Magic)
Compulsory Evacuation Device x2
Well, there it is. The idea is to get endless recursion out of the fiends. Keep in mind that Lava Golem can be summoned with Puppet Magic. Quite often, I play archfiend's raor just to get food for Puppet Magic. I also like puppet magic - ing one Archfiend to summon another, and when my opponent looks puzzled, play Dimension Fusion
. Bersek Dragon is not a problem, since LV8 monsters are always going to and from the grave. Keep in mind that 4 + 4 = 8.
