第二場決鬥無強謙論(No Pot of Duality in second Duel)
要講解這個理論之前先介紹強謙這張卡
Introduce this card below：
強欲而謙虛之壺 通常魔法
從我方牌組上方翻開3張卡，從其中選1張加入手札，剩下的卡片回到牌組洗牌。「強欲而謙虛之壺」1回合只能發動1張，此卡發動的回合我方不能特殊召喚怪獸。
強欲で謙虚な壺 通常魔法
「強欲で謙虚な壺」は１ターンに１枚しか発動できず、
このカードを発動するターン、自分はモンスターを特殊召喚できない。
(1)：自分のデッキの上からカードを３枚めくり、
その中から１枚を選んで手札に加え、
その後残りのカードをデッキに戻す。
Pot of Duality Normal Spell
Excavate the top 3 cards of your Deck, add 1 of them to your hand, also, after that, shuffle the rest back into your Deck. You can only activate 1 "Pot of Duality" per turn. You cannot Special Summon during the turn you activate this card.
這張卡能夠提前將三回合之後會抽到的牌選一張先加入，
可以看情況選合適的招，非常強。
This card can add one of third cards after 3 turns, and choose the suitable card, very strong.
但是有幾個缺點：
1.發動後這回合不能特召
會影響戰術的速度
2.手上有兩張只能發動其中一張
意思是這回合少一張能用的牌
3.雷王或岔子在場的時候不能用
意思是抽到這張都跟沒抽牌一樣慘
There is several weakness：
1.You cannot Special Summon during the turn you activate this card.
This weakness will delay speed of strategy.
2.When you draw 2 "Pot of Duality ", you can only activate 1.
That means we lack 1 card can be used in this turn.
3.You can't activate this card when Rai-oh or Mistake on the field.
Then you will be pitiful as can't draw any card.
所以假如情況允許的話
可以考慮在三戰兩勝備牌制中
第二場的時候把強謙換到備牌增加流暢度
If condition meet, we can consider change Pot of Duality into side in second game for MATCH.
好處如下：
1.換完備牌後能夠呈現40張完剋的狀態，所以不需要強謙了。
2.可以讓人不知道第二場換上的備牌(強謙本身會洩漏卡片訊息)
3.防止卡到冰火手等特召的牌
4.強謙本身也不會因為抽到兩張而只能用一張(可以考慮換完備牌只留一張)
The strength is：
1.If you can make a Full-Anti deck(with 40 cards), then it will be without Pot of Duality.
2.We can let opponent know no side cards in second game(Pot of Duality will reveal the information of cards).
3.Prevent from locking the effect of monsters can special summon like Fire hands and Ice hands.
4.You can't only activate 1 for you draw 2 "Pot of Duality " case.(Also can consider put only one "Pot of Duality ".)
以反主流強攻為例：
使用此理論，能夠發揮最大的效益時，會滿足以下條件：
1.主牌3張強謙的反主流強攻
有人會問為什麼都要換下去了，主牌還需要放三張？
當然是因為第一場不知道對手使用的牌組，
所以放入強謙可以提高穩定性，看情況拿剋對手的牌。
2.換完備牌後能夠呈現40張完剋的狀態
假如能夠換完之後都剋對手的話，盡可能減少強謙數量會比較好
可以讓每一張牌都有即時戰力，但是假如牌不夠的情況，
還是可以考慮留著，當然假如後攻需要特召來解場的情況，也是建議拿掉。
For example as Meta-beat：
With this theorem, when we can take full advantage of benefit, then will satisfy this condition below：
1.Meta-Beat with 3 Pot of Duality：
Someone may ask：All pots kicked out of main, why do we put 3 Pot of Duality？
Of course, you don't know the deck of opponent for first game, then put 3 Pot of Duality can make the deck more stable, choosing the card anti opponent according to situations.
2. The deck becomes to Full-Anti state by changed side.
If we can make the deck full-anti, then reduce the number of Pot of Duality as possible.
This tip can let every card have fighting-force instantly, but if your side is not enough, this card can also be kept. And if you need special summon to solve when second play, then supposed to kick out this.
