If they Summon low-stat monsters such as " Gladiator Beast Murmillo" and you use "Skill Drain", you now have a free attack target. It takes away all of the power from the Decks in the current Metagame. " Skill Drain" is a great Anti-Meta card.Great against " Yubel", " Mecha Phantom Beast", " Relinquished". " Book of Moon" flips a monster into face-down Defense Position, which has many useful purposes such as negating attacks, stopping certain effects and preventing your opponent from Synchro Summoning by flipping the Tuner face-down.Another example would be to negate the effect of " Number 17: Leviathan Dragon" to prevent it from gaining any attack while it still detaches its Xyz Material for the cost, or you can negate the effect of " Wind-Up Zenmaines" so that it doesn't destroy any card with it's effect. This can be useful for negating the effects of " Number 39: Utopia", to prevent it from negating attacks. This card is also useful for negating an Xyz Monster's effects, since all Xyz Monsters have to detach their Xyz Material to activate their effects. This can be useful for negating cards such as " Black Rose Dragon", " Stardust Dragon", " Legendary Six Samurai - Shi En" etc. It has 1700 ATK and its effect can be used to negate a Special Summoned monster's effect once per turn.
" Justice Bringer" Is also a decent anti-meta card.Just make sure not to use your own monster effects while this card is on the field. This card can also negate monster effects that activate from the hand, such as " Honest" and " Gorz the Emissary of Darkness". This can be really annoying for your opponent to work around if they Summon a big monster such as " Dark Armed Dragon" or " Judgment Dragon", they'll have to use up extra cards to destroy it before they can use their effects. " Doomcaliber Knight" is a great beatstick with 1900 ATK and a solid 1800 DEF, and Tributes itself to negate a monster's effect.It can also be sent to the Graveyard to negate a Special Summon, which can usually be game-ending. It has 1900 ATK and it can jam " Gadgets", " Reinforcement of the Army", " Sangan", " Charge of the Light Brigade", " Gladiator Proving Ground", " E - Emergency Call", " Black Whirlwind", " Prophecy", and other cards that add cards from your Deck to your hand other than drawing. " Thunder King Rai-Oh" is arguably one of the best Anti-Meta monsters.This card is great against " Tragoedia", " Maiden with Eyes of Blue", " Neo-Spacian Grand Mole", " Miracle Fusion", " Gorz the Emissary of Darkness", " Battle Fader", " Royal Decree", etc. It cannot attack, use its effects nor be used for a Tribute, Synchro, Xyz or Fusion Summon. After you call a card, it effectively becomes useless for the turn. " Psi-Blocker" is a very powerful card in the Anti-Meta.
