Konami also has a misconception about Yugioh - Yugioh does not need OTKs to make it an exciting game. 10-15 turn games aren't always more "exciting", but are more adrenaline packed. Players create mind games and put pressure on themselves, and triumphing through all the psychological stress is what makes Yugioh so fun. Prolonging that stress increases the enjoyment of the game. However, Konami seems to prefer the solitaire approach, where players essentially show each other their hands and see who drew better, i.e. the Dark Strike Format in 2009.
So with this in mind, we look at March 2010. Konami's #1 priority is to sell Six Samurai to the TCG. The hype around Samurai is warranted, because the deck is flat out amazing. Gateway of the Six is without a doubt what makes Samurai work more so than any other card, and losing it would greatly cripple Six Samurai down to a tier 1.5 deck. Konami can't sell people a tier 1.5 deck - they want to sell the best. However, Konami must be careful and not piss off their OCG base, because let's be honest - Konami could give a fuck about offending the TCG. When the OCG is angry, Konami listens. As a result, Gateway will be put to 2. Still very playable, but a shade less consistent than before. TCG players will still want to play Samurai and OCG players will be grateful Konami atleast did "something".
I do believe that Konami will ban Cold Wave, because Cold Wave does not promote any current product. They are aware of the strong player base that hates Cold Wave, and will listen and act accordingly. I will reiterate though - Konami will only ban Cold Wave because it is convenient for them.
I do not believe Konami will ban Monster Reborn, because Reborn is an iconic card of the game. For years Yugi has been Reborning Dark Magician, and like wise, little kids love bringing back their best monster for free.
Konami will put Royal Tribute to 1, because they stumbled upon a discovery - players love Gravekeeper. I expect within the next year more Gravekeeper support, and flat out banning Royal Tribute would discourage a lot of players from playing the archetype and buying more product. However, Konami also doesn't want games to be borderline FTK, which Royal Tribute often does. Leaving it at 1 will still allow that wacky luck factor that Konami is notorious for.
Konami will not restrict Solemn Warning. It will be reprinted within the next year in the TCG, and players will buy that product, because they will reason that they just saved $30+ by buying the reprint as opposed to buying DREV or trading. Solemn Warning being left at 3 has nothing to do with the card's effects itself. It is a rightfully hyped up card that one day will fill Konami's wallet again.
Pot of Duality has the same fate of Warning. However, Duality also has no business being put to 1, because it was nerfed so hard (only use 1 per turn, and no special summoning). So if you are praying for Duality to 1 or 2, go cry in a corner lol.
I am 100% sure that Konami will put Book of Moon to 2, because Book is the most reliable answer to preventing synchro summons. Konami wants little kids to synchro for their Stardusts, but they can't do it when Book is used in 3's in almost every deck. Konami needs to continue selling the synchro mechanic, and so, Book will go to 2.
Konami will not hurt any current tier 1 decks in play - X Sabers, Blackwings, and Plants. They are all pieces of future sets in the TCG and OCG. Each deck also has a solid fan base, which Konami will exploit.
Lastly, there will be a Russian Roulette on the banned list. I expect Tsukuyomi, Time Seal, or Magician of Faith to come off the banned list, although none rightfully should. Every now and then Konami likes testing the water with random ideas, and this banned list I anticipate them to take more risks than usual.
So if I got a dollar every time I said "Konami", I'd have a lot of dollars. I got tired of typing that damn company name out so much. But hopefully you got a deeper understanding of how they do business, and you can prepare for the new format accordingly. Thank you for reading :)
