So, I have wanted to build this type of deck for a long time and I have loved Berserk Dragon since I first saw it in the Anime.
The aim of the deck is to drop massive beat sticks on the field and when your overwhelmed opponent gets over it, you then drop a 3500 monster that attacks everything.
Well, here is the deck list; will explain choices lower down as always.
x3 Berserk Dragon
x3 Beast King Barbaros
x3 Malefic Stardust Dragon
x2 Malefic Cyber End Dragon
x2 Doomcaliber Knight
x2 Thunder King Rai-Oh
x3 A Deal with Dark Ruler
x3 Forbidden Lance
x2 The Seal of Orichalcos
x2 Mystical Space Typhoon
x1 Dark Hole
x1 Monster Reborn
x3 Stardust Dragon
x2 Cyber End Dragon
x3 Hieratic Sun Dragon Overlord of Heliopolis
x2 Number 40: Gimmick Puppet - Heaven's Strings
x1 Number 15: Gimmick Puppet - Giant Killer
x1 Number 22: Franken
x1 Number 50: Blackship of Corn
x1 Maestroke the Symphony Djinn
x1 Gem-Knight Pearl
Reason for choices: x3 Berserk Dragon - I am not taking it down from 3, as there have been MANY times I have used all three of them in one game. Dropped this three times is completely broken. It is also Train-In food and you can SS from deck OR hand, so it isn't exactly dead in your hand.
x3 Stardust/x2 Cyber End - Played around with the numbers between these two Malefic monsters and 3 Malefic Stardust was better, due to the protecting effect of the field spell.
Doomcaliber and TKRO - Because 2400 stun monsters are just amusing to watch your opponent squirm under.
x3 Forbidden Lance - Amazing card, as you all know. I love three because of damage step damage.
x2 Seal of Orichalcos - Would be 1, but I want to get it as soon as possible. Might take it out for an extra Terraforming or something.
x2 Trade-In - Found it really cloggy at 3, so bumped down to 2 and it works fine, imo.
If you want me to clarify any other choices, let me know.
You know, you could just play a bunch of copies of Demise of the Land instead of your second Seal. You probably need more defensive Traps and a way to make your Monsters more consistent and less dead. Also, why not play a Geartown engine? It seems like it'd be really good.
I really don't like Demise of the Lands, if I am honest! The Geartown engine isn't bad, but can be a real pain at times. I might look into it once more, but when I tested last time, it didn't run smoothly.
Apart of me wants to fit in Demise, King of Armageddon, because it would be fairly easy to summon.
Well the reason the Geartown engine is strong is because you can dump the Gadjiltron Dragon to Trade-In and then summon it later ... which is basically amazing, because the real engine is just 3 Geartown 2 Gadjiltron. Re: Demise - I'm not sure about that, card disadvantage is a bit ... eh. Definitely an interesting idea, though.
If you don't like Demise of the Land play more Terraforming. Deckthin is always useful.
