Nyu, I concur. The cards look a bit too...fragmented. Anyway, Goldd isn't really the kind of monster you can just slap on and use effectively. Your only own means of discarding the bugger for use is Card Destruction. One card to play two otherwise seriously subpar monsters? Not too cool, imo. Anyway, if your whole point is to punish your opponent for discard effects - as opposed to making use of them yourself - then wouldn't Reign-Beaux be more like it? It will be a bit worse a draw than Goldd but when it does pay off it does so with a vengeance. That really seems more like a side-deck thing for me, though. Either go full dark world or save them for specific match-ups. Also, dare I ask what insidious plan you have in mind for Penguin Knight?
As for the six samurai: the best way to counter them is mass-destruction, because their key ability is sacrificing partners to save themselves, so Lightning Vortex, Mirror Force, and Torrential Tribute are the most effective, I guess. Also, there's Great Shogun Shien to take into account. That only one spell or trap per turn limitation makes it all the more essential to kill monsters off in bulk. Basically, the six samurai look like so:
The Six Samurai - Irou
Warrior / Effect
4 Star / Dark
1700 Atk / 1200 Def
"While you control another ""Six Samurai"" monster with a different name, if this card attacks a face-down Defense Position monster, destroy the monster immediately with this card's effect without flipping it face-up or applying damage calculation. If this card would be destroyed, you can destroy another ""Six Samurai"" monster you control instead."
The Six Samurai - Kamon
Warrior / Effect
3 Star / Fire
1500 Atk / 1000 Def
"Once per turn, while you control another ""Six Samurai"" monster with a different name, you can destroy 1 face-up Spell or Trap Card. This monster cannot declare an attack during the turn this effect is used. If this card would be destroyed, you can destroy another ""Six Samurai"" monster you control instead."
The Six Samurai - Nisashi
Warrior / Effect
4 Star / Wind
1400 Atk / 700 Def
"While you control another ""Six Samurai"" monster with a different name, this card can attack twice during the same Battle Phase. If this card would be destroyed, you can destroy another ""Six Samurai"" monster you control instead."
The Six Samurai - Yaichi
Warrior / Effect
3 Star / Water
1300 Atk / 800 Def
"Once per turn, while you control another ""Six Samurai"" monster with a different name, you can destroy 1 Set Spell or Trap Card. This monster cannot declare an attack during the turn this effect is used. If this card would be destroyed, you can destroy another ""Six Samurai"" monster you control instead."
The Six Samurai - Yariza
Warrior / Effect
3 Star / Earth
1000 Atk / 500 Def
"While you control another ""Six Samurai"" monster with a different name, this card can attack your opponent directly. If this card would be destroyed, you can destroy another ""Six Samurai"" monster you control instead."
The Six Samurai - Zanji
Warrior / Effect
4 Star / Light
1800 Atk / 1300 Def
"While you control another ""Six Samurai"" monster with a different name, destroy any monster this card attacks at the end of the Damage Step. If this card would be destroyed, you can destroy another ""Six Samurai"" monster you control instead."
Grandmaster of the Six Samurai
Warrior / Effect
6 Star / Earth
2100 Atk / 800 Def
"You can only have 1 ""Grandmaster of the Six Samurai"" monster on your side of the field. While you control a face-up ""Six Samurai"" monster, you can Special Summon this card from your hand. When this card is destroyed by your opponent's card effect, add 1 ""Six Samurai"" monster from your Graveyard to your hand. "
Great Shogun Shien
Warrior / Effect
7 Star / Fire
2500 Atk / 2400 Def
"If you control 2 or more ""Six Samurai"" monsters, you can Special Summon this card from your hand. Your opponent can activate only 1 Spell/Trap Card each turn. If this card would be destroyed, you can destroy a ""Six Samurai"" monster you control instead."
As you can see, the only ones with real bulk are Shien and Grandmaster. Generally, it seems like Six Samurai like to hide behind traps (Sakuretsu Armor, Mirror Force, and what-have-you) and pick off opponents with their awesome card effects while any samurai that do get killed are brought back with The Warrior Returning Alive, Premature Burial, and Call of the Haunted. So yeah, kind of a swarming strategy, I guess, because those little buggers get onto the field right quick. >.< Grandmaster and Shien are a serious menace because they special summon easily and particularly in combo. (Normal summon a Six Samurai, special summon Grandmaster, and special summon Shien for great field dominance) and because they're warriors they of course have access to easy monster search and return (Like letting Grandmaster die to bring back another samurai, after which Grandmaster is brought back with The Warrior Returning Alive and special summoned).
