To fight against amazing search power of spellbooks, there are a couple of cards that will completely stop then in their tracks. The first card is a card called thunder king rai-oh. this card has a great ability to stop spellbooks in a heart beat. Thunder king rai-oh's effect is:
Neither player can add cards from their Deck to their hand except by drawing them. During either player's turn, when your opponent would Special Summon a monster: You can send this face-up card to the Graveyard; negate the Special Summon, and if you do, destroy it.
Summon this bad boy, and there it is, no more searching for them spellbooks. the most important thing to know is that you cant search either when you have him in the field, so make sure you do your searching before you summon him. you also need to be able to protect your thunder king. if you can protect your thunder king, you will win the game. the next card that is great against spellbooks is called drill and lock bird. drill and lock birds effect is:
If your opponent adds a card(s) from their Deck to their hand, except during the Draw Phase, you can send this card from your hand to the Graveyard. For the rest of this turn, neither player can add card(s) from their Deck to their hand. (Drawing cards is also considered as "adding a card to the hand.")
This card will stop spellbooks in their track for one turn. once they activate spell books of secrets to search spellbook of judgements, you can send this card to the graveyard and stop them from adding more cards from their deck to their hand. Now this last card is the best cards against spellbooks, but harder to use against them because of the condition needed to use this card. This card is called eradicator epidemic virus. This cards effect is:
Tribute 1 DARK monster with 2500 or more ATK, and choose Spell Cards or Trap Cards; check your opponent's hand, all Spell/Trap Cards they control, and all cards they draw until the end of their 3rd turn after this card's activation, and destroy all cards of the chosen type.
THIS CARD IS GREAT! if you can manage to activate this first turn, you will most likely win this duel. There are 2 decks that can easily get a dark monster out first turn that are popular right now, evilswarm and dragon ruler. evilswarm can just summon evilswarm ophion first turn and activate it while dragon ruler will summon number 11 big eye first turn and activate it.
There ya go, the weakness to spellbooks, enjoy burning down them books!
