Nope, this is not about any new changes to the game which allows us to have 5 copies of a card in the deck, but as everyone knows, after Thunder King Rai-Oh became semi-limited, it has become harder to deal with the top decks right now, which includes Dragon Rulers and Prophecy.
However, there's no need to worry because Konami is here to save the day! Well, they were the ones who started this problem, but nonetheless, they are trying to atone for their mistakes. As I was feeling rather bored today, I decided to browse through Shriek OCG and started to look through the card list for the new upcoming OCG set, "Shadow Specters".
While I was reeling back in joy seeing how War Gods aka Bujin is going to wreck the meta with their new support cards in this set, I managed to chance upon a card that was sitting right at the bottom of the post for "Shadow Specters". This card is none other than "Mistake".
Continuous Trap Card
Effect: While this card is on the field, neither player can add card(s) to their hand except by drawing.
The effect sounds familiar? Yes, Thunder King Rai-Oh has this effect as well! So despite Rai-Oh being limited, Konami did try to make up for the last piece of Rai-Oh by creating this card.
We all know how good Rai-Oh is, so there's no need to waste any words to verify its credentials. However, with a new side-deck buddy in the form of "Mistake" now, it's time to stop Prophecy decks from using their "Spellbook of Secrets", "Spellbook of Judgment", "Prophecy of Justice" and "Spellbook Magician of Prophecy"!
Furthermore, this card will be awesome against Dragon Rulers as well. If they banish an adult dragon to special summon another adult dragon, you can use "Mistake" to prevent them from adding their baby dragons from deck to hand.
Well, obviously "Mistake" won't be as good as "Thunder King Rai-Oh", but as least it is a new side-deck option against the top decks right now.
